Though I didn't take any pictures during my tour, I did manage to hold on to a couple of souvenirs from those days.
This was the badge that we all wore on the breast pocket of our uniforms. It's about 1 3/4" in diameter and had two pins on the back which were secured by standard ribbon clips -- what we Air Force types used to call dammit clips. They were called that because that's what one said when they slipped off. Which they did. Often.
