I am aware of 18 different Hallmark backings to the Distinguished Eagle Device Pin. The Hallmark can be found on the back side of the pin. Most are on the tail, but one is displayed on the wing. If you have a Hallmark that I am missing, or know of a different variety please contact me. I can either purchase it from you or trade you for a different DESA Device pin.
