Click the picture to see a larger more detailed image. Marked "Button-up" and "Copyright 1984 John Cougar Inc." around the rim.  1 3/8" diameter. We uncovered them very recently in an old vending warehouse here locally. 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. Excellent unused condition.
