Sub-Mariner Comics #25

From 1948, this ten-cent Timely gem pits Sub-Mariner and Namora against a villain nursing a lifetime of hatred for humanity — Firebrand. The cover by Mike Sekowsky throws you right into the chaos: a muscular, bare-chested man grapples with the fierce blonde Namora on a shoreline, while a red-bearded figure in military dress shouts desperately — "You've gone mad, Firebrand! Mad! Mad!" — as a woman in red stands bound near a crackling fire. Writer Bill Woolfolk and artist Ken Bald bring "Firebrand, the Scourge of the Pacific" to vivid life inside, making this a wonderfully atmospheric slice of Golden Age adventure.
