Marked "Button-up" and "Copyright 1986 W.A.S.P." around the rim. These are from around the 1986 Last Command tour. These licensed types are very scarce, yet easy to identify by the licensing info on the side of the button. Most of the musical pinbacks that you see for sale on eBay or other online sites are reproductions.

These licensed types retail for much higher prices. We uncovered them very recently in an old vending warehouse here locally. Excellent unused condition.
