The Biff Tannen Museum was a museum constructed by the corrupt toxic waste company BiffCo and it was dedicated to Biff Tannen's "illustrious" life in the alternate 1985 timeline. There was a documentary at the entrance which Marty McFly watched after he traveled back home after a brief trip to 2015, hoping to be in the 1985 he knew. The museum documentary shows video footage of Biff and Lorraine Baines McFly's wedding. While here, the shocked Marty was found and knocked out by Match, Skinhead and 3-D.
