Hello all, I have been collecting autographs since the mid 90's. My first autograph being Dr J. Julius Erving himself. I travel to many large events to give myself the opportunity to offer a wide variety of autographs for you guys and look forward to dealing with you in the future. Please feel free to message me with any questions that you may have.

Collectors: Happy with your purchase from this seller?

Do NOT do business with Matt, he will led you on for days or weeks and never pay. Not trust worthy.

Matthew is condescending, rude, short, and unprofessional. He chastises people if they don’t see the prices within a listing, and he lists items deceptively.
There’s a reason his $2000 Barack Obama signed book hasn’t sold. Prices are unreasonable and has no customer engagement or service. Stay far, far away.
