Vintage Indonesian Dayak Tribal Face Brooch

Pricing & History
Vintage 1940's brooch featuring the face of the Dayak tribal person with stretched/elongated earlobes, and a Borneo ceremonial hat. No visible mark (looks like one was there but it's too worn in that spot), but all of the others we found are sterling silver. The Dayak (Dyak, Dayuh) is a generalized name for some of the tribal people of Indonesian Borneo (Kalimantan).
