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?

I cannot be grateful enough to Matthew Griese (Blue line signatures) for this amazing piece, one of my top grails 🙏 special packaging, amazing communication, and amazing price …I can be a challenging buyer as I have many requests and questions. He answered them all with the kindest replies… He also put this aside for me for a couple of months until the JSA LOA came back!

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