Vintage “Choppers ‘til you die” Enamel Lapel Pin

Another pin from my friend’s Harley jacket. I photographed this amazing vintage pewter (I believe) and midnight black enamel “Choppers ‘til you die” lapel pin” on the back of my sleeping granddog! That’s an Ohio State University dog sweater-GO BUCKEYES!!!!!!!!! Beautiful vintage condition-no bends, scratches or missing enamel/The enamel is solid black but shows some reflections.
