Justice League of America #44

In "The Plague That Struck the Justice League!", the League finds itself suddenly and inexplicably doubling in size, prompting a visit from the seemingly helpful alien doctor, Dr. Bendorion. As Batman grows suspicious of the doctor’s true intentions, the line between healer and threat begins to blur—setting up a tense confrontation that challenges the team’s trust in the very aid meant to save them. Written by Gardner Fox and illustrated by Mike Sekowsky, with inks by Frank Giacoia and letters by Gaspar Saladino, the cover by Mike Sekowsky and Murphy Anderson captures the eerie scale of the crisis.
