Sea Devils #22

Rising from the crashing surf, a towering alien sea creature — its body writhing with tentacle-like appendages and marked with a strange symbol — looms over a rocky shoreline where three figures in distinctive red-and-white diving suits scramble in alarm, while a whale breaches dramatically in the background. Howard Purcell's cover art for this 1965 DC title captures the Sea Devils facing a genuinely unsettling oceanic menace, promising the kind of undersea sci-fi adventure the series delivered so well. Bob Haney's script and Purcell's interior art bring "Operation Sea Terror" to life in what looks to be a memorably strange chapter for this team of aquatic adventurers.
