Photograph of Pima Indian Papajo's burro and horse carrying pottery ollas to market in Phoenix, ca.1900. The burro stands in profile on sandy ground rutted with wagon tracks and headed to the right, one olla is strapped on to the near side of the donkey by a net. The horse stands at right facing the burro but looking straight ahead, while another olla is strapped on its near side. The animals are unattended. They were trained to stand still when their reins touch the ground. Several bare trees line the road at right. A wagon with two passengers is visible in the background.
