This is a Sepik River tribal mask from Papua New Guinea that I purchased from a really nice estate. The mask is unbelievably beautiful. Its height is 30" and its width is about 19". There are wild boars tusks protruding from the nose and  native bird feathers that adorn the upper edge and  the eyes of the mask.   The upper perimeter is missing some shells but that doesn't at all detract from its over all appeal. You be the judge.     Thanks for looking.
