This is a wonderful very attractive old unmarked early 1900s 3 1/8" by 3 1/8" gold gilt metal frame with a 2 3/8" by 2 3/8" insert area in back for photo. Features embossed beaded scrolls and sweet enamel beading. Only has one tab on back to hold in cardboard. Works fine with only one. Under a loupe I see a few beaded areas has enamel loss. I first thought it was the design. Looks fine the way it is. Has nice easel. Stands nicely and sweet in person. Has no glass and not sure if ever did. Lovely well cared for condition. You should be pleased. Thanks for looking.
