This rare 1960 button has an orange-ish/tan cardboard reverse with horizontal brass pin. There is no maker name. Front displays totally clean with exception of tiny 1/8" thread trapped under cello at lower right. Also at this same area is a slight shallow depression in the celluloid about 1x1.25" but this shows just a little. The entire piece has full gloss and no stain. Only example we've seen. Rare.
