Huge 1920s Button Mottled Mottled Celluloid 2 7/8 Diameter

This is a 1920s vintage mottle patterned brown celluloid button that a flapper would have worn on a dress at the side of the hip. The button is quite large, measuring 2 7/8 in diameter. The celluloid is wrapped around a rigid core with a black back. There are two holes drilled to the centre. It is in very good original condition.
These large buttons are difficult to find - great addition to a button collection or simply to use on a garment!
