From the 40's A Celluloid Cameo on Wood with a Celluloid Chain. The wood background is 2 1/2 inch circle and Celluloid cameo with a tan Celluloid Chain. I think that the wood is Olive Wood. This piece is unmarked but because of the design you can tell the era. This is an interesting jewelry piece and it is in excellent shape. It will come in a velvet bag with gift box ready to give as that special gift. From the High Plains of Kansas!
