Very old hand mirror picture frame 1920s no glass

This is a unique piece. No doubt originally part of a dresser set, this is the hand mirror that has no mirror. Instead it is a frame for an original wedding photo from the 1920s. This came from an estate sale and the owner said her grandparents were in the photo but she had no information other than that. It's beautiful marbled green, probably celluloid. There are scratches on the frame side commensurate with age, and a small stain on the green side that is difficult to see. Approximate measurements: 15" long and 5" at widest point.
