I think it is possible that “Captain Comet, Space Pilot” may have been intended for another publication. Eastern Color, also known as Famous Funnies, published 12 issues of Buster Crabbe comics between 1951-1953. In reviewing the issues I see that Al Williamson did a couple of stories for them. Today’s posting could have been originally intended for Buster Crabbe, but was not published. It appeared in Danger Is Our Business #1 (1952) instead, with the Buster Crabbe name changed. Not only that, “Captain Comet” was a character being published by DC Comics in Strange Adventures, appearing from 1951 to 1954. If I had been a comic book publisher in those days I would have worried about running afoul of DC’s lawyers, in light of the ongoing Superman/Captain Marvel lawsuit which dragged on for years, finally settled in 1953.
The “Space Pilot” story itself is drawn by Williamson and Frank Frazetta, and for fun it features space pirates. The pirate captain is a descendant of Captain Kidd, so he wears a skull-and-crossbones on his chest. I like the artwork, but am indifferent to the story...except for the pirate chief.
Toby Press published Danger Is Our Business, and the first issue was reprinted in 1958 by I.W. reprint comics, from which my scans are taken.
