At St. John, writer Norman Maurer and artist Kubert created the enduring character Tor, a prehistoric-human protagonist who debuted in the comic "1,000,000 Years Ago" (Sept. 1953). Tor immediately went on to star in "3-D Comics" #2-3 (Oct.-Nov. 1953), followed by a titular, traditionally 2-D comic-book series, written and drawn by Joe Kubert, that premiered with issue #3 (May 1954). The character has since appeared in series from Eclipse Comics, Marvel Comics' Epic imprint, and DC Comics through at least the 1990s. Kubert in the late 1950s unsuccessfully attempted to sell "Tor" as a newspaper comic strip. The "Tor" samples consisted of 12 daily strips, reprinted in six pages in "Alter Ego" vol. 3 #10 and later expanded to 16 pages in DC Comics' "Tor" #1. He contributed work to Avon Periodicals, where he did science-fiction stories for Strange Worlds and other titles.
