Fiction House was a major publisher of pulp magazines and comics through the 1950s. Their comics came out of a pulp tradition with stories of jungle heroes (Sheena, Queen of the Jungle), air aces (Wings Comics), westerns (Cowgirl Romances), science fiction (Planet Comics), and, of course, Jumbo Comics (Action! Adventure! Mystery!).

The first time travel that I tracked down here was an adventurer named Stuart Taylor who teamed with Dr. Hayward and his beautiful daughter Lora (later Laura) in many issues of Jumbo Comics. For me, it was exciting for two reasons: (1) It’s some of the earliest time travel in a comic book that I know of; (2) At least the first few stories were drawn by Jack King Kirby (as by Curt Davis). Time travel probably occurred in 1-4 (“The Experiment of Kromo”), as well as in 5-14, 17-78, 84-139, plus a reprint in 140. (Numbers 15-16 had no time travel; I think 79-83 are shorter, with no Stuart Taylor, and Stu disappeared after 140.)

Note: I should get The Complete Jack Kirby, Volume 1, which has the first three Kromo reprinted in black and white, to verify that they have time travel.>

Their science fiction comic, Planet Comics, had at least one bout of time travel when a chronoscope brought dinosaurs and such to The Lost World of heroes Hunt and Lyssa (Planet Comics 41, March 1946); it also short, 2-page stories, at least one of which was time travel (“Lost World of Time” in Planet Comics 7, July 1940).
