The Osborn Mansion is the home of Norman Osborn and Harry Osborn.
History[]
Norman Osborn threw a dinner party at his mansion for Harry's birthday. Several people attended such as Peter Parker, Mary Jane Watson, Flash Thompson, and Debra Whitman.
Smoke billows from the mansion entrance.
During the dinner Norman hinted at the fact that he knew that Peter Parker was really Spider-Man. To keep Norman from revealing his secret identity Peter threw his web cartridges into the fireplace. The fire heated up the chemicals causing a smoke screen. Everyone though the mansion had caught on fire and ran outside. Inside Spider-Man fought Green Goblin.
