Challengers of the Unknown #11

From the eerie skies of a 1959 DC adventure, the cover of Challengers of the Unknown #11 hurls readers straight into chaos — a massive winged green dragon-creature, fitted with glowing mechanical eyes that fire blasting energy beams, bears down on the four purple-suited Challengers scrambling desperately across the ground below. Bob Brown's cover art captures both the alien menace and the team's very human vulnerability with vivid, unsettling energy. "The Creatures from the Forbidden World" promises exactly the kind of science-fantasy danger that made this series one of DC's most imaginative offerings of its era.
