John Carter, Warlord of Mars #10

Marvel's adaptation of Edgar Rice Burroughs' Barsoomian saga reaches a fever pitch in this 1978 issue, bringing the "Air-Pirates of Mars" storyline to its dramatic conclusion. Gil Kane's cover art — both penciled and inked by Kane himself — thrusts a fierce, mohawked Martian warrior front and center, blades drawn and teeth bared, while John Carter battles furiously in the background amid the chaos of combat. The cover's bold challenge — "Is This the Death of Barsoom?" — makes this final chapter of the Air-Pirates arc one you won't want to put down.
