This is an original Antique / Vintage Wood Mask from East Java or possibly the island of Bali. My guess is this piece most likely dates from the early to mid 1930's. The lower jaw is loosely held to the upper jaw with two rubber pieces nailed into the wood. Mask Dimensions: 8 inches long, inches high, 5 3/4 inches wide by 3 1/2 inches in depth.
Weight: 6.6 ounces (186 grams). Don T Christensen, Penang, Malaysia.
