Picture 22 of 47
One of the exhibits in the Benjamin Franklin Court Museum is a diorama called Franklin's World Stage. In a twelve minute show, three scenes from Benjamin Franklin's life are illustrated.
Before each scene started, a different platform with the central characters in that scene would mechanically rise up from the floor in the framed area in the center of the picture. I took this picture before the show started so I wouldn't distract people from the show with camera flashes.
