Hey y'all. This autograph was owned by my grandfather and it's been around my house since before I was born, so I believe he was the first owner.
he died 8 years ago and my interest in knowing about its authenticity has only grown on me recently. We've decided to sell it, could you help me tell if its authentic? And the date, what year it is? I recognize the 7 but not the following number
Thnx very much
