Here is a wonderful old pin which depicts a string instrument. It is made in silvertone metal with wonderful detail, considering it is tiny in size. It has a pin catch on the back which has the patent date: "2383012". The patent dates to the mid-1940's.
The pin measures approximately 1" in length X 3/8" W. It is in very good condition and has not been tested for silver content. A neat piece for a man, woman or child who plays a string instrument such as the violin, cello, etc.
