We participate in many local and out of state public and private signings. We also understand that making these signings can be impossible. So, we are proud to do the legwork for you. If you would like to get the autograph of an athlete we have advertised, we will be more than happy to take your item, and have it signed by that player for you. We know how valuable and sentimental your item is to you. You can rest assured that our professional GDA staff will handle your item with the upmost professionalism and as if it were our very own.

We will always have blank officially licensed items for you to purchase if you do not have an item to be signed.

If you have a special pen that you want your item signed with, you must include the pen/s with your item. We try very hard to accommodate any special requests. But with these signings, we cannot guarantee it.

Third party authentication is also available at a cost. Third party authenticators include (PSA/DNA, JSA, Beckett Witnessed)

Please keep in mind that we try our very best to accommodate your all your requests. However, all players reserve the right to not sign or limit / change inscriptions on an item for any reason. Furthermore, we will not ask the signee to add inscriptions to previously signed items.
