Anthropomorphic figure with two faces

This curious sculpture, whose body tapers to a point (perhaps due to a functional or ritual purpose), features a dual, naturalistic face, likely representing a man and a woman.
One side is adorned with scarifications on the chin representing a tattoo.
The other side shows a smiling face. The torso is symmetrically rendered.
The tip is engraved (with ears, eyes, and a toothed mouth) to depict an animal’s head, likely a bear.
