The one to the left is barefoot, wears glasses and holds a bell in his right hand, a stick and probably a book in his left hand. The man to the right holds a leather strap in his left hand. With his right hand he points to the other man. In the background a road and bushes. Imprinted on the image: "2 christl. Hottentotten. Süd-Afrika-West. No. 513." ("2 Christian Hottentots. South Africa West. No. 513."). The photo was taken in the Western part of South Africa.
