A man of the Dani tribe in Irian Jaya walking down a road in the Baliem Valley, close to Wamena, the principal town of the highlands. The traditional men's dress is no more than a shaped gourd used as a penis sheath, or horim (called koteka in Indonesian) tied around the testicles at the base, sometimes with a cord securing the tip to the man's chest. The Dani are Melanesian..
