Rare bagpipe pin; great hat device!

This beautiful oval pin was created by Vietnam veteran W. R. “Gunz” Gunzelman of “Art by Gunz.” Some of his other creations can be seen on Amazon.  It has an emerald green background with two concentric silver colored rings at the perimeter. The center contains a correctly depicted GHB with drone ribbons. Beneath that is “U.S.A.” and under that, along the bottom edge is “Eirinn go Brach”.  Height is 1-1/2” and width is 1-1/8”.  It makes a great hat device for a glengarry, balmoral, tam or baseball cap.  The pin is secured at rear by two standard clutch back retainers. Price includes $6 for USPS domestic shipping  by ground.  Click on each picture to expand them.  Thanks for looking.
