Blackhawk #183

This 1963 DC two-parter drops the Blackhawk Squadron into a naval nightmare, with uniformed heroes on deck firing rifles skyward at a menacing purple flying fish-bomb while a second creature explodes on the water's surface nearby and a sleek enemy vessel looms in the background. The cover blurb asks the unsettling question of what other fantastic weapons Killer Shark has waiting — a villain with a sea fortress at his disposal clearly isn't short on imagination. Dick Dillin's pencils and Chuck Cuidera's inks bring it all to vivid, kinetic life, capturing that perfect blend of pulp adventure and Cold War-era tension that made Blackhawk such a fun read.
