Blackhawk #50

Blackhawk #50 from Quality Comics plunges the whole squad into deep-sea danger with the featured story "The Killer Shark?" — and Reed Crandall's cover makes the threat viscerally clear, showing Blackhawk himself fighting underwater against a monstrous, wide-jawed shark while a submerged aircraft looms ominously in the murky background. The banner copy — "Into the sea they fled… leaving cities paralyzed from their merciless attacks!" — sets a genuinely unsettling tone, and the portrait medallions of the full Blackhawk team rimming the title remind you just how much is at stake for the whole squadron. A ten-cent thrill from 1952 that captures Crandall's crisp linework at its most dramatic.
