1.75" dia. with silver luster rim surrounding double sided glass insert that held normally appears simply as a two-sided mirror with muted silvering. When the piece is held to light clearly revealed is a black and white photo of a woman in full figure using both hands to pull up the corners of a voluminous fabric dress thus revealing her shoes, above the knee black stockings with garters, and a small portion of a bare leg. Extreme outer edge of the photo is missing scattered tiny spots of gray color but the image itself is about 98% complete and quite sharp. Only example we've seen.
