American Comics Group was a historical American comic-book publisher active mainly from the 1940s through the 1960s. Its publishing program centered on comic periodicals and anthologies covering adventure, horror, science fiction, and humor. ACG issued titles such as Adventures into the Unknown, Forbidden Worlds, and Unknown Worlds, using anthology structures common to American comics while also relying on recurring characters and serialized features to distinguish its publications.
