Thanks, Carlton and Steve,
I did get a message out to the Natick Historical Society and hope that they are able to confirm the "signature" as I am already quite sure that the image is indeed of Harrison Harwood.
What I did take note of on the print itself is that the engraver, A.H. Ritchie, was renowned in the field in the mid to late 19th century and did many engravings of famous people and events...Washington, Lincoln, Continental Congress, etc.
So, I wait for some info from Natick, Mass. and hope that I've got a genuinely signed, 19th century print of the man who founded the very first company to manufacture baseballs in the United States.
