I'm still educating myself but would appreciate the input of people more knowledgeable ... I'm guessing these signatures on eBay are fan club facsimiles masquerading as the real thing?
Yup...Autopen. The Fan Club sent these out from late 1963 until...I think...1968. They all had the same first name only "signatures. Some cards had all 4 "signatures" in black ink...and others had 2 in black and 2 in blue. These turn up on Ebay as being signed...but they're not.
