Kid Colt Outlaw #114

The cover by Jack Kirby and Sol Brodsky makes the threat immediately clear: the hulking, armored Iron Mask looms in the foreground, bullets sparking harmlessly off his metal helmet as he vows revenge, while a determined Kid Colt on horseback faces him down in the background. Stan Lee and Gene Colan deliver the 18-page book-length Marvel Super-Spectacular that the cover banner promises fans demanded — "The Return of Iron Mask!" — and the setup of a completely bullet-proof villain versus a gunslinger armed only with grit is a genuinely compelling western dilemma. If you enjoy Marvel's 1964 frontier adventures at their most action-forward, this is a satisfying pick.
