Vintage Pearl Treble Clef Music Lapel Pin

This pretty treble clef is made of mother of pearl which has carved detailed. Attached to the back is a pin with a simple c-closure. I believe this is from the 1950's – 1960’s. It measures about 2” long by 1 1/8” across; penny for scale. It is in very nice condition with minor wear on back (See picture).
