caption: The image shows an old black and white photo of a machine with gears on it, sitting on the floor in front of a wall. The machine appears to be an automaton, with a large wheel in the center and several smaller wheels radiating outwards from the center. The wheel is surrounded by a metal frame and has a handle on the side for easy maneuvering. The wall behind the machine is plain and unadorned, with no other objects in the frame.
