- —Doc to Marty
Doc Brown and Marty McFly's photograph of the clock was taken on September 5, 1885 at the Hill Valley Festival, and was later deposited in the City Archives of the Hill County Courthouse, until Doc and Marty discovered it in 1955.
Originally, Doc chose to stand next to the clock alone for a photo, undoubtedly since he was the only person who witnessed the clock start and stop. However, when Marty joined Doc in 1885, it was actually Marty's idea to have their photograph taken next to the clock, since he wished he had brought his camera.
It is possible that after the photo was taken, Marty's image would have appeared on the photo from the City Archives that he brought with him to the past, but upon his return to 1985, the left half of the photo had burned up when the DeLorean was destroyed.
After Doc returned to 1985 at the site of the DeLorean time machine's destruction, he gave Marty the completed photograph as a memento.
It is unknown as to whether a copy of the same photograph also ended up in the City Archives as a replacement for the damaged original (featuring only Doc) that Marty took with him back to 1885.
