Before being bought by DC, All-American Publications had a 102-issue run with All-American Comics, which among other things introduced the Green Lantern and had an adaptation of Carl H. Claudy’s A Thousand Years a Minute in issues 7 through 12. However, the episode in #7 was actually more the wrapping up of an earlier serial (also by Claudy and under the umbrella of Adventures in the Unknown) called “The Mystery Men of Mars,” and the actual time-traveling began until issue 8.
