I have a 1989 sports illustrated signed "all the best" signed Michael Jordan #23. With a ticket from a exhibition game in 1991 bulls/nets at the breslin center. I dont know if its real. I found it in a box of my dads things. Along with a mantle signed ball, Ted Williams signed ball and other Jordan stuff. Did he sign many things back then? Can anyone send me a certified signature from back then? Email is hawaiinb@gmail.com. also signed in red marker. Can anyone help me, I don't wanna spend the money on a cert if its not real. If you email me I can send a pretty good pic to if that helps. Thank you very much
