Justice League of America #37

In "Earth--Without a Justice League!", the Johnny Thunder of Earth-One seizes control of his Earth-Two counterpart's Thunderbolt after a mistaken teleportation, setting off a chain of time-warping chaos. With the help of the sentient Thunderbolt, he alters history to erase the Justice League’s origins, creating a Lawless League from his criminal allies to challenge the JSA on Earth-One. Written by Gardner Fox and illustrated by Mike Sekowsky, with inks by Bernard Sachs and lettering by Gaspar Saladino, this 1965 classic features a cover by Mike Sekowsky and Murphy Anderson that captures the high-stakes, reality-bending tension of the story.
