Captured in Nushagak, Alaska, this 1912 photo shows an Eskimo medicine man, also known as an Aglegmiut shaman, with his arm draped over the shoulder of a sick boy. It was captioned "Working to beat the devil" - exorcising evil spirits from a sick boy. Despite being forbidden by Christian missionaries, these ceremonial costumes, consisting of masks and outsized hands, were still made and used in the early 1900s by the Aglegmiut people.
