A Vintage Photos Theme Park photo for the theme of in costume.

This is an undated snapshot of a flag-bedecked automobile with a driver who's dressed in a suit and top hat. Next to him in the front seat is Uncle Sam himself. Two other costumed passengers — they must be George and Martha Washington! — are riding in the back seat. Perhaps these are the celebrity guests in a Fourth of July parade.

See a cropped version of the photo for a close-up of Uncle Sam and his friends.
