Space Adventures #57

This Charlton sci-fi anthology from 1964 poses a tantalizing question right on its cover: "Who Were 'The Spell-Casters'?" — and the painted tension in Dick Giordano's cover art makes you genuinely want to find out. Three astronauts in red pressure suits are caught in a moment of alien menace on an otherworldly landscape, while an unseen presence taunts them with "Give up, weak Earthlings!" as a rocket stands ready in the background. Joe Gill and Bill Molno bring the interior story to life, making this a satisfying slice of early-'60s space-age storytelling at its most imaginative.
