Green Lantern #87 (1971)

Green Lantern #87 (1971) marks a significant moment in the comic book world as it introduces John Stewart as the first African-American Green Lantern. The story begins with the Guardians of the Universe, the creators of the Green Lantern Corps, recruiting Stewart as a backup for Hal Jordan after Guy Gardner suffers an injury. Jordan, initially unimpressed with Stewart's hostile nature towards authority, ends up being impressed with his bravery after he saves a police officer from a shooter at a rally led by a racist Senator, Jeremiah Clutcher. Stewart goes on to prove that Clutcher was behind his own assassination attempt, allowing him to gain sympathy votes for his presidential campaign.

"What Can One Man Do?" features Green Arrow, and this issue also includes "Earth's First Green Lantern!" originally published in Green Lantern #16. As a collector, Green Lantern #87 holds incredible historical significance as it marks a pivotal moment in comic book history.
