Last October I bought a very nice drum decal, though it is only
11-1/2 inches in diameter, the size used on band organs.

Thomas Born <bluewatereagle@yahoo.com> of Rochester, Minnesota,
has printed a number of these, as well as the large Wurlitzer
lettering.  His price is $75 plus postage for the round decal.

I spent several years trying to find one.  Hope this helps for you,
Larry, and anyone else looking.
