Gorilla-Man is an alias used by three different fictional superheroes appearing in American comic books published by Marvel Comics , beginning in 1954 with the character of Kenneth Hale , and continuing with Arthur Nagan , who also first appeared in 1954, and Franz Radzik , who first appeared in 1962.
95-1169: The character of Kenneth Hale first appeared in Men's Adventures #26 (March 1954). Dr. Arthur Nagan first appeared in Mystery Tales #21 (Sept. 1954), and was created by Bob Powell . This story was reprinted in Weird Wonder Tales #7 (Dec. 1974). Steve Gerber created the Headmen after reading the reprint issue. The character subsequently appears in The Defenders #21 (March 1975), 31–33 (January–March 1976), 35 (May 1976), The Defenders Annual #1 (Oct. 1976), Power Man/Iron Fist #68 (April 1981), Marvel Age Annual #1 (1985), The Sensational She-Hulk vol. 2 #1–3 (May–July 1989), Avengers: Deathtrap: The Vault Graphic Novel (1991), Web of Spider-Man #73 (Feb. 1991), Marvel Comics Presents #97 (1992), The Defenders vol. 2 #5 (July 2001), 7–10 (Sept.–Dec. 2001), and Heroes for Hire #6–8 (March–May 2007). Gorilla-Man appeared as part of
190-410: A Russian expedition led by Fabian Gottlieb von Bellingshausen and Mikhail Lazarev . The decades that followed saw further exploration by French, American, and British expeditions. The first confirmed landing was by a Norwegian team in 1895. In the early 20th century, there were a few expeditions into the interior of the continent. British explorers Robert Falcon Scott and Ernest Shackleton were
285-527: A few blue-ice areas , the wind and sublimation remove more snow than is accumulated by precipitation. In the dry valleys, the same effect occurs over a rock base, leading to a barren and desiccated landscape. Antarctica is colder than the Arctic region, as much of Antarctica is over 3,000 m (9,800 ft) above sea level, where air temperatures are colder. The relative warmth of the Arctic Ocean
380-587: A few Dark Elves infiltrate the mountain. While recovering, he talks to Odin and it's later revealed that he betrayed the Avengers for Dracula 's Legion of the Unliving. He's later seen helping Ka-Zar and Blade in fighting Roxxon's Berserkers when infiltrating their secret base in Antarctica . Dr. Arthur Nagan is a former surgeon who took the organs from gorillas to use in people. However, his scheme
475-456: A larger group seeking to stop the heroin shipments. They discover a vast underground empire, looking to control all crime above ground. Working together, the heroes manage to obliterate the criminal group. As part of the 2016 Marvel NOW! branding, Gorilla-Man appears as a member of Domino 's incarnation of the Mercs for Money . Black Panther later visits Gorilla-Man and persuades him to join
570-409: A man who admires evil things is injected with a formula by an evil scientist which turns him into an ape, as he hopes to become a creature of evil. A student is knocked out by the evil man. He is tied to a chair and gagged at the home of the scientist. The mind of the man is sent back through the ages as he becomes an ape. However, the other man is able to free himself. He breaks the scientist's neck, but
665-525: A mild climate. West Antarctica was partially in the Northern Hemisphere , and during the time, large amounts of sandstones , limestones , and shales were deposited. East Antarctica was at the equator, where seafloor invertebrates and trilobites flourished in the tropical seas. By the start of the Devonian period (416 Ma ), Gondwana was in more southern latitudes, and the climate
760-457: A native bacterial community within the subterranean water body of Lake Vostok . The existence of life there is thought to strengthen the argument for the possibility of life on Jupiter 's moon Europa , which may have water beneath its water-ice crust. There exists a community of extremophile bacteria in the highly alkaline waters of Lake Untersee . The prevalence of highly resilient creatures in such inhospitable areas could further bolster
855-431: A newly introduced character mysterious until a "secret origin" issue. Some fans consider this a gimmick and prefer the older method. The artistic merit of many first appearances is debatable. The events portrayed in most famous first appearances are continuously retconed , rebooted and/or expanded upon by subsequent writers. Like many golden and silver age comics, first appearances often become dated and do not fit
950-701: A number of mountain ranges in the region, the most prominent being the Ellsworth Mountains. The presence of the West Antarctic Rift System has resulted in volcanism along the border between West and East Antarctica, as well as the creation of the Transantarctic Mountains. East Antarctica is geologically varied. Its formation began during the Archean Eon (4,000 Ma–2,500 Ma), and stopped during
1045-461: A party Alicia Masters was hosting to procure Spider-Man's body for Chondu. Human Torch and Spider-Man defeated the enemies and the Headmen were soon arrested. Later allied with the A.I.M., they plotted to control an ancient space-god to rule the world. They resurrected the alien space god Orrgo and conquered the world with him, but the Defenders quickly defeated Orrgo and the Headmen. Nagan and

#17327916837631140-579: A scientist who created an electromagnetic ray machine to transfer his mind into a gorilla's body was known as Gorilla-Man. He was sent into deep space on an experimental rocket ship and first appeared in Tales to Astonish #28 and 30. The former story was reprinted in Adventure into Fear #5, the latter in Gorilla Man #3 . NOTE : This is not to be confused with a story from Strange Tales #1. In it,
1235-655: Is 1–3 cm (0.39–1.18 in). From the end of the Neoproterozoic era to the Cretaceous , Antarctica was part of the supercontinent Gondwana . Modern Antarctica was formed as Gondwana gradually broke apart beginning around 183 Ma. For a large proportion of the Phanerozoic , Antarctica had a tropical or temperate climate , and it was covered in forests. During the Cambrian period , Gondwana had

The lakes that lie at the base of the continental ice sheet occur mainly in the McMurdo Dry Valleys or various oases . Lake Vostok , discovered beneath Russia's Vostok Station ,
1425-521: Is an experienced transplant surgeon and inventor. His large gorilla body possesses immense physical attributes. The Franz Radzik version of Gorilla-Man has similar powers as the other two, but it left him unable to speak. In an alternate Earth that appears in Avengers Forever #4–5, a similar version of Hale as Gorilla-Man appeared in the Avengers of the 1950s. Their timeline was destroyed by Immortus . On Earth-O-Men, Ken Hale appears as
1520-480: Is being revealed by techniques such as remote sensing , ground-penetrating radar , and satellite imagery . Geologically, West Antarctica closely resembles the South American Andes . The Antarctic Peninsula was formed by geologic uplift and the transformation of sea bed sediments into metamorphic rocks . West Antarctica was formed by the merging of several continental plates , which created
1615-427: Is captured and caged at the local zoo. As Gorilla-Man, Kenneth Hale possesses the body of a mountain gorilla, while retaining his normal human intelligence. He has access to various weapons with a preference for firearms . Even as a human, he is skilled at fighting. Hale also has been cursed with virtual immortality and maintained the same level of physical prowess over decades. The Arthur Nagan version of Gorilla-Man
1710-449: Is caused by the emission of chlorofluorocarbons and halons into the atmosphere, which causes ozone to break down into other gases. The extreme cold conditions of Antarctica allow polar stratospheric clouds to form. The clouds act as catalysts for chemical reactions, which eventually lead to the destruction of ozone. The 1987 Montreal Protocol has restricted the emissions of ozone-depleting substances. The ozone hole above Antarctica
1805-711: Is divided into West Antarctica and East Antarctica by the Transantarctic Mountains , which stretch from Victoria Land to the Ross Sea . The vast majority of Antarctica is covered by the Antarctic ice sheet , which averages 1.9 km (1.2 mi) in thickness. The ice sheet extends to all but a few oases , which, with the exception of the McMurdo Dry Valleys, are located in coastal areas. Several Antarctic ice streams flow to one of
1900-470: Is evidence of a large number of volcanoes under the ice, which could pose a risk to the ice sheet if activity levels were to rise. The ice dome known as Dome Argus in East Antarctica is the highest Antarctic ice feature, at 4,091 metres (13,422 ft). It is one of the world's coldest and driest places—temperatures there may reach as low as −90 °C (−130 °F), and the annual precipitation
1995-408: Is expected to add about 11 cm (5 in) to global sea level rise . Marine ice sheet instability may cause West Antarctica to contribute tens of centimeters more if it is triggered before 2100. With higher warming, instability would be much more likely, and could double global, 21st-century sea-level rise. The fresh, 1100-1500 billion tons (GT) per year of meltwater from the ice dilutes

#17327916837632090-582: Is predicted to slowly disappear; by the 2060s, levels of ozone are expected to have returned to values last recorded in the 1980s. The ozone depletion can cause a cooling of around 6 °C (11 °F) in the stratosphere . The cooling strengthens the polar vortex and so prevents the outflow of the cold air near the South Pole, which in turn cools the continental mass of the East Antarctic ice sheet. The peripheral areas of Antarctica, especially
2185-441: Is the largest subglacial lake globally and one of the largest lakes in the world. It was once believed that the lake had been sealed off for millions of years, but scientists now estimate its water is replaced by the slow melting and freezing of ice caps every 13,000 years. During the summer, the ice at the edges of the lakes can melt, and liquid moats temporarily form. Antarctica has both saline and freshwater lakes. Antarctica
2280-504: Is transferred through the Arctic sea ice and moderates temperatures in the Arctic region. East Antarctica is colder than its western counterpart because of its higher elevation. Weather fronts rarely penetrate far into the continent, leaving the centre cold and dry, with moderate wind speeds. Heavy snowfalls are common on the coastal portion of Antarctica, where snowfalls of up to 1.22 m (48 in) in 48 hours have been recorded. At
2375-402: Is widely considered to have solidified, if not created, the superhero archetype; therefore, his first appearance is not only important to fans of the character but to fans of superheroes and comic books as a whole. Well-preserved copies of Action Comics #1 have been sold at auction for record-breaking prices. A copy graded at 8.0 ("very fine") on the 10-point scale typically used by collectors
2470-721: The Agents of Wakanda . During The War of the Realms storyline, Gorilla-Man is seen talking to Ursa Major in the Wundagore Zoo in Transia , discussing about an undercover operation he's running for Black Panther, until Ka-Zar picks him up and takes him to Avengers Mountain. He helps Black Panther destroy the enemy forces that were attacking the mountain by activating a weapon inside the Celestial's body, but gets wounded after
2565-664: The Antarctic Circle (one of the five major circles of latitude that mark maps of the world), Antarctica is surrounded by the Southern Ocean . Rivers exist in Antarctica; the longest is the Onyx . Antarctica covers more than 14.2 million km (5,500,000 sq mi), almost double the area of Australia, making it the fifth-largest continent, and comparable to the surface area of Pluto . Its coastline

Models suggest that ozone depletion and the enhanced polar vortex effect may also account for the period of increasing sea ice extent, lasting from when observation started in the late 1970s until 2014. Since then, the coverage of Antarctic sea ice has decreased rapidly. Most species in Antarctica seem to be

The Ken Hale incarnation of Gorilla-Man appears as a playable character in Lego Marvel Super Heroes 2 via the " Agents of Atlas " DLC pack. First appearance In comic books and other stories with a long history, first appearance refers to the first issue to feature a fictional character . These issues are often highly valued by collectors due to their rarity and iconic status. Collectors value first appearances for their rarity and historical value, while many regular readers are interested in viewing how their favorite characters were originally portrayed. Reprints of first appearances are often published, both as single comic books and in trade paperbacks , usually with other early appearances of
4370-669: The Headmen then fought the Heroes for Hire while attempting to transplant Chondu 's head onto Humbug 's body. It is revealed in the Guardians of the Galaxy series that Nagan is one of the inmates left behind in the Negative Zone 's Prison 42. There, he is involved in a fight with Star-Lord , who is trying to stop Blastaar and his horde from invading Earth via the closed portal in the prison. He sided with Blastaar's forces when

4655-593: The West Antarctic, the ocean has warmed by 1 °C (1.8 °F) since 1955. The warming of the Southern Ocean around Antarctica has caused the weakening or collapse of ice shelves , which float just offshore of glaciers and stabilize them. Many coastal glaciers have been losing mass and retreating, causing net-annual ice loss across Antarctica, although the East Antarctic ice sheet continues to gain ice inland. By 2100, net ice loss from Antarctica
4750-634: The argument for extraterrestrial life in cold, methane -rich environments. The first international agreement to protect Antarctica's biodiversity was adopted in 1964. The overfishing of krill (an animal that plays a large role in the Antarctic ecosystem) led officials to enact regulations on fishing. The Convention for the Conservation of Antarctic Marine Living Resources , an international treaty that came into force in 1980, regulates fisheries, aiming to preserve ecological relationships. Despite these regulations, illegal fishing —particularly of
4845-416: The biodiversity in Antarctica is still at risk from human activities. Specially protected areas cover less than 2% of the area and provide better protection for animals with popular appeal than for less visible animals. There are more terrestrial protected areas than marine protected areas . Ecosystems are impacted by local and global threats, notably pollution , the invasion of non-native species , and

Historically, first appearances tell the origin story for the character, although some, such as Batman and Green Goblin , remained dubious figures for several issues. Modern writers prefer to tell a character's origin across an entire story arc or keep
5130-466: The climate cooled, though flora remained. After deglaciation during the latter half of the Early Permian , the land became dominated by glossopterids (an extinct group of seed plants with no close living relatives), most prominently Glossopteris , a tree interpreted as growing in waterlogged soils, which formed extensive coal deposits. Other plants found in Antarctica during the Permian include Cordaitales , sphenopsids , ferns, and lycophytes . At

It is mainly a polar desert , with annual precipitation of over 200 mm (8 in) along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost 60 metres (200 ft). Antarctica holds
5320-404: The colonial authorities in Sydney officially renamed the continent of New Holland to Australia, leaving the term "Terra Australis" unavailable as a reference to Antarctica. Over the following decades, geographers used phrases such as "the Antarctic Continent". They searched for a more poetic replacement, suggesting names such as Ultima and Antipodea . Antarctica was adopted in the 1890s, with
5415-423: The continent as a World Park . The Southern Ocean Whale Sanctuary was established in 1994 by the International Whaling Commission . It covers 50 million km (19 million sq mi) and completely surrounds the Antarctic continent. All commercial whaling is banned in the zone, though Japan has continued to hunt whales in the area, ostensibly for research purposes. Despite these protections,
5510-599: The continent's edge, strong katabatic winds off of the polar plateau often blow at storm force . During the summer, more solar radiation reaches the surface at the South Pole than at the equator because of the 24 hours of sunlight received there each day. Climate change caused by greenhouse gas emissions from human activities occurs everywhere on Earth, and while Antarctica is less vulnerable to it than any other continent, climate change in Antarctica has been observed. Since 1959, there has been an average temperature increase of >0.05 °C/decade since 1957 across

West Antarctica warmed by over 0.1 °C/decade from the 1950s to the 2000s, and the exposed Antarctic Peninsula has warmed by 3 °C (5.4 °F) since the mid-20th century. The colder, stabler East Antarctica had been experiencing cooling until the 2000s. Around Antarctica, the Southern Ocean has absorbed more oceanic heat than any other ocean, and has seen strong warming at depths below 2,000 m (6,600 ft). Around

The lowest natural air temperature ever recorded on Earth was −89.2 °C (−128.6 °F) at the Russian Vostok Station in Antarctica on 21 July 1983. A lower air temperature of −94.7 °C (−138.5 °F) was recorded in 2010 by satellite—however, it may have been influenced by ground temperatures and
6080-553: The end of that period. During the colder Neogene (17–2.5 Ma), a tundra ecosystem replaced the rainforests. The climate of present-day Antarctica does not allow extensive vegetation to form. A combination of freezing temperatures, poor soil quality , and a lack of moisture and sunlight inhibit plant growth, causing low species diversity and limited distribution. The flora largely consists of bryophytes (25 species of liverworts and 100 species of mosses ). There are three species of flowering plants , all of which are found in

Smaller forms of life, such as sea cucumbers and free-swimming snails , are also found in both polar oceans. Factors that may aid in their distribution include temperature differences between the deep ocean at the poles and the equator of no more than 5 °C (9 °F) and
6555-435: The genus Dicroidium , which grew as trees. Other associated Triassic flora included ginkgophytes , cycadophytes , conifers , and sphenopsids. Tetrapods first appeared in Antarctica during the early Triassic , with the earliest known fossils found in the Fremouw Formation of the Transantarctic Mountains. Synapsids (also known as "mammal-like reptiles") included species such as Lystrosaurus , and were common during
6650-469: The globe to balance the northern lands of Europe, Asia, and North Africa—had existed as an intellectual concept since classical antiquity . The belief in such a land lasted until the European discovery of Australia . During the early 19th century, explorer Matthew Flinders doubted the existence of a detached continent south of Australia (then called New Holland ) and thus advocated for the "Terra Australis" name to be used for Australia instead.

Hale abandoned his goal at the last minute, but his encounter with the Gorilla-Man forced him to shoot. The story follows that Hale then became immortal, but at the cost of becoming a Gorilla-Man himself. After operating his own team for a while, Hale retired, residing in a large treehouse near
7030-467: The main human activities in and around Antarctica. During the summer months, about 5,000 people reside at research stations , a figure that drops to around 1,000 in the winter. Despite the continent's remoteness, human activity has a significant effect on it via pollution , ozone depletion , and climate change . The melting of the potentially unstable West Antarctic ice sheet causes the most uncertainty in century-scale projections of sea level rise , and
7125-814: The major current systems or marine conveyor belts which are able to transport eggs and larva . About 1,150 species of fungi have been recorded in the Antarctic region, of which about 750 are non- lichen -forming. Some of the species, having evolved under extreme conditions, have colonised structural cavities within porous rocks and have contributed to shaping the rock formations of the McMurdo Dry Valleys and surrounding mountain ridges. The simplified morphology of such fungi, along with their similar biological structures , metabolism systems capable of remaining active at very low temperatures, and reduced life cycles, make them well suited to such environments. Their thick-walled and strongly melanised cells make them resistant to UV radiation. An Antarctic endemic species,
7220-671: The many Antarctic ice shelves , a process described by ice-sheet dynamics . East Antarctica comprises Coats Land , Queen Maud Land , Enderby Land , Mac . Robertson Land , Wilkes Land , and Victoria Land. All but a small portion of the region lies within the Eastern Hemisphere . East Antarctica is largely covered by the East Antarctic Ice Sheet . There are numerous islands surrounding Antarctica, most of which are volcanic and very young by geological standards. The most prominent exceptions to this are
7315-517: The modern portrayal of the character.

7410-587: The north'). Antarcticus is derived from the Greek ἀντι- ('anti-') and ἀρκτικός ('of the Bear ', 'northern'). The Greek philosopher Aristotle wrote in Meteorology about an "Antarctic region" in c. 350 BCE . The Greek geographer Marinus of Tyre reportedly used the name in his world map from the second century CE, now lost. The Roman authors Gaius Julius Hyginus and Apuleius used for
7505-578: The ocean around Antarctica, including some that normally reside in the Arctic. The emperor penguin is the only penguin that breeds during the winter in Antarctica; it and the Adélie penguin breed farther south than any other penguin. A Census of Marine Life by some 500 researchers during the International Polar Year was released in 2010. The research found that more than 235 marine organisms live in both polar regions, having bridged
7600-408: The origin never improves on the original, they simply expand it." First appearances of popular characters are among the most valuable comic books in existence. Of the "ten most valuable comic books" listed in the spring 2002 issue of The Overstreet Comic Book Price Guide , seven are first appearances of popular superheroes . Another, Marvel Comics #1 (October 1939), is the first appearance of
7695-797: The pristine condition prized by collectors. What few remain can be worth thousands of dollars to interested collectors. For example, in 2004, a copy of Flash Comics #1 (January 1940), the first appearance of The Flash , was auctioned for $ 42,000 and a copy of Captain America Comics #1 (March 1941), the first appearance of Captain America sold for $ 64,400. In 2010, another copy of Flash Comics #1 sold privately for $ 450,000. The first appearance of Superman , Action Comics #1 (June 1938), has been regarded as " holy grail " of comic books, due to its cultural significance and rarity (fewer than one hundred copies are thought to exist). Superman
7790-424: The record for the lowest measured temperature on Earth , −89.2 °C (−128.6 °F). The coastal regions can reach temperatures over 10 °C (50 °F) in the summer. Native species of animals include mites , nematodes , penguins , seals and tardigrades . Where vegetation occurs, it is mostly in the form of lichen or moss . The ice shelves of Antarctica were probably first seen in 1820, during
7885-539: The saline Antarctic bottom water , weakening the lower cell of the Southern Ocean overturning circulation (SOOC). According to some research, a full collapse of the SOOC may occur a between 1.7 °C (3.1 °F) and 3 °C (5.4 °F) of global warming, although the full effects are expected to occur over multiple centuries; these include less precipitation in the Southern Hemisphere but more in
7980-480: The same melting also affects the Southern Ocean overturning circulation , which can eventually lead to significant impacts on the Southern Hemisphere climate and Southern Ocean productivity. The name given to the continent originates from the word antarctic , which comes from Middle French antartique or antarctique ('opposite to the Arctic ') and, in turn, the Latin antarcticus ('opposite to
8075-406: The species of fungi, which are apparently endemic to Antarctica, live in bird dung, and have evolved so they can grow inside extremely cold dung, but can also pass through the intestines of warm-blooded animals. Throughout its history, Antarctica has seen a wide variety of plant life. In the Cretaceous , it was dominated by a fern- conifer ecosystem, which changed into a temperate rainforest by
8170-683: The sub-Antarctic islands. The flightless midge Belgica antarctica , the largest purely terrestrial animal in Antarctica, reaches 6 mm ( 1 ⁄ 4 in) in size. Antarctic krill , which congregates in large schools , is the keystone species of the ecosystem of the Southern Ocean, being an important food organism for whales, seals, leopard seals , fur seals, squid , icefish , and many bird species, such as penguins and albatrosses . Some species of marine animals exist and rely, directly or indirectly, on phytoplankton . Antarctic sea life includes penguins , blue whales , orcas , colossal squids and fur seals . The Antarctic fur seal
8265-592: The treaty. Instead, countries adopted the Protocol on Environmental Protection to the Antarctic Treaty (the Madrid Protocol), which entered into force in 1998. The Madrid Protocol bans all mining, designating the continent as a "natural reserve devoted to peace and science". The pressure group Greenpeace established a base on Ross Island from 1987 to 1992 as part of its attempt to establish
8360-470: The various effects of climate change . Early world maps, like the 1513 Piri Reis map , feature the hypothetical continent Terra Australis . Much larger than and unrelated to Antarctica, Terra Australis was a landmass that classical scholars presumed necessary to balance the known lands in the northern hemisphere. Captain James Cook 's ships, HMS Resolution and Adventure , crossed
8455-412: The water when it freezes, which accumulates into pockets of brine that also harbour dormant microorganisms. When the ice begins to melt, brine pockets expand and can combine to form brine channels, and the algae inside the pockets can reawaken and thrive until the next freeze. Bacteria have also been found as deep as 800 m (0.50 mi) under the ice. It is thought to be likely that there exists
8550-529: Was cooler, though fossils of land plants are known from then. Sand and silts were laid down in what is now the Ellsworth, Horlick , and Pensacola Mountains . Antarctica became glaciated during the Late Paleozoic icehouse beginning at the end of the Devonian period (360 Ma), though glaciation would substantially increase during the late Carboniferous . It drifted closer to the South Pole, and
8645-855: Was detained by Justice . Gorilla-Man was later behind a hostage crisis until he was defeated by Captain Ultra . During the "Opening Salvo" part of the " Secret Empire " storyline, Gorilla-Man appears in an underground lair where he was building his army of Gorilla-Men while operating under the alias of King of the Gorilla-Men. These Gorilla-Men are the results of gorilla heads being surgically-attached to human bodies. He then finds Robert Maverick who just turned back from his Red Hulk form. While attempting to pull Robert's head out of his body to strengthen his Gorilla-Men army, Gorilla-Man and his Gorilla-Men are attacked and defeated by Squirrel Girl , who unleashes her flying squirrels on his army. Franz Radzik ,
8740-472: Was not recorded at a height of 2 m (7 ft) above the surface as required for official air temperature records. Antarctica is a polar desert with little precipitation ; the continent receives an average equivalent to about 150 mm (6 in) of water per year, mostly in the form of snow. The interior is dryer and receives less than 50 mm (2 in) per year, whereas the coastal regions typically receive more than 200 mm (8 in). In
8835-493: Was sold at auction for $ 1,000,000 in 2010. Even a copy graded at a much lower 5.5 ("fine minus") sold for $ 956,000 in 2016. Shortly after the record-breaking million-dollar sale of Action Comics #1 in 2010, a copy of Detective Comics #27 featuring the first appearance of Batman was sold for $ 1,075,000 in a Heritage auction. Several factors determine the value of a first appearance. Note: All values are according to ComicsPriceGuide.com and are for editions certified by
