Rampaging Hulk #6

The cover of this December 1977 black-and-white magazine from Marvel pulls no punches: the Hulk hoists an enormous boulder overhead while a bare-chested Sub-Mariner lunges at him with a weapon in hand, their clash set against an eerie underwater realm populated by monstrous creatures and an armored warrior woman lurking in the shadows behind them. Ken Barr's painted cover work gives the whole scene a brooding, painterly weight that suits the promise of a "Duel in the Dark Depths." With the tagline heralding a "Shattering Conclusion: Showdown with the Sub-Mariner," this is a satisfying payoff issue for anyone who loves Marvel's two most ornery powerhouses going at it beneath the waves.
