Justice League of America #45

In "The Super-Struggle Against Shaggy Man!", the Justice League of America faces a double threat: the unstoppable Shaggy Man and a massive rock creature. With a clever twist, the Flash proposes turning the two monsters against each other—setting the Shaggy Man loose on his rocky foe, then pitting him against a duplicate of himself. Written by Gardner Fox and illustrated by Mike Sekowsky, with inks by Frank Giacoia and Joe Giella, and lettering by Gaspar Saladino, this 1966 classic features a dynamic cover by Mike Sekowsky and Murphy Anderson.
