Vintage Chinese Opera Face Painting Miniatures Masks Collectible Decorative Art

Vintage Chinese Opera Face Painting Miniatures Masks Collectible Decorative Art. From left to right: Hsu Ch'ou, Chang Fei, Kawn yu, Ma Wu. Each mask is about 2.5" tall x 2" at widest. They are mounted inside a cardboard box with a glass top. Box is roughly 9.5" long x 3.5" tall x 1.5". Some wear on box from age and storage. Masks appear to be made out of a lightweight material (they are glued into place and I can't tell if they are like a paper mache or ceramic) Will be packed with care.
