Note: Adventures Into the Unknown was a series best known as the medium's first ongoing horror-comics title. The first two issues, which included art by Fred Guardineer and others, featured horror stories of ghosts, werewolves, haunted houses, killer puppets, and other supernatural beings and locales. The premiere included a seven-page abridged adaptation of Horace Walpole's seminal gothic novel The Castle of Otranto, by Frank Belknap Long and Al Ulmer. Unlike many American horror comics of the Golden Age, it weathered the public criticism of the early 1950s and survived the aftermath of the Senate Subcommittee on Juvenile Delinquency hearings of April and June 1954 when the comics industry attempted self-regulation with a highly restrictive Comics Code.

Note: Canadian editions may also exist. A copy of issue #9 was advertised as Canadian on Ebay in May of 2008, unknown what (if any) difference exists between editions.
