Justice League of America #105

In "Specter in the Shadows!", the Justice League of America faces its first real test when the Elongated Man is gravely injured during a battle with the alien Putty-Men, leaving the team reeling—only to be rescued by a shadowy figure whose true identity remains a mystery. Written by Len Wein and brought to life by Dick Dillin’s dynamic art and Dick Giordano’s sharp inks, this 1973 issue marks a pivotal moment in the JLA’s early years, with a cover by Dick Giordano capturing the tension and intrigue of the unseen threat.
