This picture is a carving from Gjoa Haven. Gjoa Haven artist are well known for their depictions of the shamanic or spiritual world. These carvings are quite often unsettling, but gripping and fascinating. This particular carving has a bit of a Yin-Yang duality to it in that both sides (front and back) show a different face.
I believe the artist to be Kamik but are not sure. The carving is 8 by 8 by 11 inches.
