John Carter, Warlord of Mars #28

A towering, crimson-skinned Martian warrior dominates this Bob McLeod and Klaus Janson cover, shield and spear in hand, looming over a desperate battle below where John Carter and a green Martian clash against armored foes — with a woman warrior visible among the combatants. The tagline "Guardians of the Lost City!" sets up a tantalizing mystery at the heart of this 1979 Marvel adventure based on Edgar Rice Burroughs' beloved creation. Inside, writer Peter Gillis and artist Larry Hama carry the action forward in a story titled "The Weapon-Makers of Mars!" — promising plenty of Barsoomian intrigue to match that striking cover.
