Justice League of America #59

In "The Justice Leaguers' Impossible Adventure!", five members of the Justice League find themselves stranded on a strange world where their powers have been stripped away by the enigmatic trio known as the Impossibles. With no strength, speed, or abilities to rely on, they must use their wits and teamwork to face a new threat—the Contras—before it's too late. Written by Gardner Fox and illustrated by Mike Sekowsky, with inks by Sid Greene and lettering by Joe Letterese, this 1967 classic features cover art by Mike Sekowsky and Wayne Boring.
