A rider sits atop a mule that has been harnessed with a large yoke. The yoke has steel chains attached, which extend to the side and back of the mule, attaching the first mule to the mule behind him in train fashion. A young boy stands next to the second mule and holds onto its rein. The iron works can be seen in the background.
