This is a ceramic Maori style tiki head pendant.
This pendant is shaped like a traditional temple image. The tiki has wide round eyes and a gaping mouth. They were made from a Duncan brand hobbyist mold (circa 1963) and also resemble the early Coco Joe's piece pictured on pg. 167 of Tiki Quest. The headdress and body were left off of the pendant from the original mold.
