Amazing Spider-Man #121
Gwen Stacy was Peter’s love interest for several years, but this issue in June 1973 was her big moment… and her last. Norman Osborn, alias the Green Goblin, gets in a rage because he blames the webslinger for his son Harry’s drug problem, and takes his revenge by hurling Peter’s beloved off a bridge, much as Peter had always feared. But superheroes always save the day, right? Not this time. Spidey’s web reaches the plummeting Gwen, but the force of the fall breaks her neck. A dark day indeed for Spidey and shocked fans everywhere.
