This Yuat River mask is characteristic of masks from the north coast of Papua New Guinea. This example, distinguished by perforation holes along the edge of the mask used to fasten dance costumes worn by dancers in ceremonies. These masks cover the face only while the cloaks made from fibre conceal the rest of the wearer's body. Such mask is part of an impressive dance costume, attached to a conical frame placed over the dancer's head, while a long fibre skirt conceals the body. In ceremonies performed in special ceremonial grounds, the dancers dance to the flickering lights of fire torches accompanied with drums. The dancer is thought to represent or impersonates a clan spirit.
