I KNOW that someone needs this. Think of the possibilities. Measuring 18 1/2" x 12 1/2" x 3 1/2" - there is lots of room for an all bisque vignette or whatever you want to enshrine for your viewing pleasure. There is a crack in the wood back of the box that is stable. The piece is held together with two screws that go through an eye attached to the frame and there are two additional screws on the outer frame to hang the box on a wall. In wonderful antique condition with some yellowing and staining of the original paper and a few small seed bubbles in the glass.
