Kull, the Destroyer #13

From the creator of Conan comes this 1974 Marvel sword-and-sorcery entry, "Torches from Hell!" — and the cover makes the promise of that title abundantly clear. Kull himself charges forward, sword raised and shield in hand, while a massive flaming creature looms over him, its fiery body crowned by a colossal, grinning skull that dominates the upper half of the image. The cover art, penciled by Mike Ploog and John Romita and inked by Al Milgrom and John Romita, delivers a genuinely striking composition that captures the pre-human menace at the heart of Robert E. Howard's legendary barbarian king.
