Unique Plaster Violin and Notes Wall Plaques

This is kind of a unique set. Seems to me like it may have been a project set. It is a plaster of paris with a wire hook set in while wet. We have a violin with two notes for either side. They are done in black with silver highlights. Some minor paint nicks but no damage to the figures. Violin is 14” tall by 4 1/2” wide. Notes are 4” tall by 2 3/4” wide.
