This rare piece has some small condition problems but is still most attractive and unusual. The piece stands 1.5" tall and both front and back are highly convex so the depth of the piece is .25". Front center has glass cover with beveled outer edge over a cardboard photo of Lincoln. The rim edge has fancy designs, each accented by a black enamel dot and on a solid black enamel bkg. On the far left and right edges there is a narrow line each about .5" long with some small loss of the black enamel. On the brass-covered reverse, the base of the T-bar pin remains but the shank has snapped off and the loop that held the shank is slightly pushed over. Very high quality workmanship and still displays beautifully. Only example we've seen.
