Was Erich Von Däniken the first to tie flying saucers to ancient civilizations?
The idea of aliens visiting us in ancient times had been popular for as long as fantasy and science fiction have been around.
Inspired by the flying saucer craze of the late 1940s-early 1950s, this 1950 Wally Wood-illustrated book was one of many one-shot titles from Avon Comics during their short, but prolific existence.
Another one-shot (though it probably wasn't intended to be such), was Fawcett's Vic Torry and His Flying Saucer (1950).
Flying saucers also popped-up in almost every already-running comic book from funny animals to mysteries.
They even appeared in Charlton's Cowboy Western Comics, which changed it's name for a year to Space Western Comics to play up the connection!
