This is a vintage geisha hair ornament. This fan shaped hair comb is open on one side with a textured background and multicolor enamel & gilded raised plum flowers and leaves. It trembles on a spring. Another arrow shaped trembler comes through the open side. There are various other dangles. This very vintage piece has wear to the enamel and other issues as pictured. It is probably a GI's momento from his time in the occupation army.
Dimensions: 5.5 x 2.5 x 1 .75 inch
