I need to know the technical definition of autograph. I have an autographed Ernie Banks with Certificate of Authenticity. He physically signed it with a blue magic marker. I also have the printed autographs from the company. For instance, I have a 1993 Leaf/Studio of Bo Jackson, with his signature in gold, silvery print across the bottom going onto his White Sox shirt. How do I list each one? The Bo is not really an autograph, it's a print. The banks really is an autograph, even if it didn't have the CoA.
