The Amazing Spider-Man # 78

Story 2: "The Night of the Prowler!"

Peter tries to see Gwen only to find that she is (apparently) on a date with Flash. Hobie approaches his boss with ideas for new safety devices for his job as window-washer, only to be rebuffed. He implements them in private, adds a cloak and a mask, and thus creates The Prowler. Hobie plans to rob a newspaper as the Prowler then return the money as Hobie, making himself a hero. Naturally Peter (as Peter) discovers the Prowler in the act and J. Jonah discovers Peter in front of an empty safe.
