Someone took this Ektachrome slide of my uncle in his newly-acquired MG around 1955, in front of his San Francisco home (on the right). Why the Caddy limo is there, or if it's connected with the event, I don't know; based on the front fender trim, I think it's a '54. Appears to be a registration certificate taped inside the windshield. I presume it's parked facing the wrong way on the street because Cadillac limos get to do that. Next-door neighbor kid seems entranced by the scene, as I would have been. View full size.
