Regarding the Attinelli Watkins reproductions, as Joel pointed out in his article, there is one copy in the library of the American Numismatic Society. With Frank Campbell's help, I discovered the Attinelli Watkins reproduction when he was ANS librarian. The ANS also has the only known original of the Watkins broadside.

I managed to find a source for high quality facsimiles a few years ago, and commissioned the production of a number of new facsimiles from the original Watkins broadside. I donated them to the ANS, and so the ANS now has a number of Watkins broadside facsimile's of the Original broadside for sale. All proceeds go to help with ANS library conservation projects. For availability and pricing, contact ANS Librarian Elizabeth Hahn at hahn@numismatics.org .
