Hello, these autographs were collected by a New York City Policeman over his lifetime. He passed away in 1999 and I acquired them from his wife several years ago. Just recently, I opened a few boxes and the cards and pictures I am listing are all from his amazing personal collection. His name was Jim, so many of the autographs are addressed to him as "Jim". They are all authentic signatures collected by him over his lifetime. His wife says he collected many of the sports stars, dignataries and celebrities in his duties as a NYC policeman, many others he collected by writing to the signers in the mail. I do not have any matching Certificates of Authenticity, as these were his personal cards and signatures for his own collection, and I have no way of matching them all up now that he is gone. I am selling these "as is", with no implied guarrantee, but with the honest expectation that they are genuine. Free shipping in the USA.
