Kamandi, the Last Boy on Earth #14

This February 1974 entry in Jack Kirby and Mike Royer's post-apocalyptic series throws Kamandi straight into the chaos of the "Sacker Sweepstakes" — a brutal contest where people are among the prizes. The cover captures the frantic energy perfectly: Kamandi in his blue shorts takes a punishing hit at the center of the action, a helmeted figure in red grapples nearby, a blonde woman scrambles desperately across the rubble, and a massive green reptilian creature dominates the right side, making the stakes viscerally clear. At just 20 cents, this is Kirby's wild, inventive Earth of the future firing on all cylinders.
