John Carter, Warlord of Mars #23

The deck of a Martian airship becomes a battlefield on this April 1979 cover, where John Carter swings into action sword raised while a scarlet-draped Dejah Thoris braces herself against the chaos below — a crowd of figures massing on the deck around them. Ernie Chan's cover art crackles with kinetic energy, capturing the desperate, high-stakes atmosphere promised by the story title "The Man Who Makes Murder!" The tagline "Murder on Mars!" sets an ominous tone for this eighth chapter of the Master Assassin saga, with Chris Claremont writing and the interior art team of Vosburg and Ricardo Villamonte bringing Edgar Rice Burroughs' world vividly to life.
