Dating from the later Victorian era, a brass frame photo pinback. The mourning or memory photo of a man measures 1-1/4" in diameter. The brass frame is simple with the straight pin back in working order.
Covering the photo, is a celluloid (or type) disc to protect the photo underneath. Some discoloration of the brass with age and scuffs to the finish of the celluloid covering. Nothing that wouldn't be expected.
