The McFly family photograph was a photograph of the three children of George McFly and Lorraine Baines McFly. From left stood Dave McFly, Marty McFly, and Linda McFly. Marty kept a copy of the photo in his wallet and referred to it when he was stuck in 1955 to prove to Emmett Brown that he was from the future. Doc noted that it must have been fake as Dave's head had disappeared from the photo after Marty's run-in with his parents.
