Even more fun...the first issue was named One Million Years Ago, while the second issue 3-D Comics, with 3 variant covers and sizes (and, the third even had additional material)....before the title of the book became Tor.
One Million Years Ago (September, 1953) and 3-D Comics #2 (1st comic, October, 1953)
3-D Comics #2 (2nd magazine, October, 1953 and 3rd comic, November, 1953)
Tor #3 and #4 (May and July, 1954)
Tor #5 (October, 1954)
Tor lived in a prehistoric fantasy world, filled with dinosaurs and sabretooth tigers...a fun and fertile playground for an artist like Kubert.
A pretty big achievement for just a caveman, but very worthy with that incredible Kubert art!
here, a covering of Ragman is here, and, a team up of Sgt. Rock and Viking Prince is here!
