Input: Question: Was the artist for "The Mighty Thor" older than both of its writers? Passage:Journey into Mystery is an American comic book series initially published by Atlas Comics, then by its successor, Marvel Comics. Initially a horror comics anthology, it changed to giant-monster and science fiction stories in the late 1950s. Beginning with issue #83 (cover dated Aug. 1962), it ran the superhero feature "The Mighty Thor", created by writers Stan Lee and Larry Lieber and artist Jack Kirby, and inspired by the mythological Norse thunder god. The series, which was renamed for its superhero star with issue #126 (March 1966), has been revived three times: in the 1970s as a horror anthology, and in the 1990s and 2010s with characters from Marvel's Thor mythos. The title was also used in 2019 for a limited series as part of the "War of the Realms" storyline.
