2 Vintage Carved Masks Mounted on Ebony in Japanese

2 Vintage Carved Masks Mounted on Ebony in Japanese Style; these carved masks are in an ivory-like material. They are mounted on blocks of ebony and show a very stylistic appearance. There are no markings. We believe they have age and our intuition is they are of Japanese origin, possibly Netsuke. The larger of the two is in excellent condition; the other is in good condition showing some chipping in the wood and chipping on the figurines lips.Each measures approximately 3" x 3" x 1 1/2". Very unique and striking.
