I was at an estate sale today and saw an autograph for sale. It was a Bo Jackson signed photo. It was framed with two Bo Jackson sports cards. I believe one of them was one of his baseball cards and the other was one of his football cards. They wanted $100 for it. Tomorrow they will be discounting all items 50% or 75% I can't remember which one. Would this autograph be worth purchasing? This photo is not the one in question but the exact same image that was at the estate sale.
