Here is a lovely miniature taken after the famous painting by François Boucher of Venus bath where she is surrounded by lots of little cherubs. The pretty painting's colors are still bright and beautiful with lots of blues. Set under a slightly convex glass in a very nice French type design ormolu frame.
It has a velvet back with the typical teeth holding it all in place. It could be opened but I have never opened it. An o-ring on the reverse for hanging. Probably made for the tourist trade in the 19th century. Likely French in origin. Please see photos for approximate measurement and details.
