Challengers of the Unknown #71

The Challengers of the Unknown find themselves in grim straits on Nick Cardy's striking cover for issue #71 — the team in their signature purple-and-yellow uniforms are bound and staggering while a menacing green-cloaked figure hurls bystanders aside, taunting onlookers with the chilling warning: "Let them be a lesson to all who dare trespass on Skull Mountain!" Cardy's dynamic linework captures both the heroes' vulnerability and the villain's sinister dominance with real flair. Titled "When Evil Calls!", this January 1969 issue promises the kind of high-stakes adventure that made this DC series a favorite for fans of daring, imaginative storytelling.
