Who We Are…

Together Greg and Matt have over 15 years of experience dealing and selling authentic autographs. They obtain each individual autograph in person and provide a detailed description of where the item was signed on a GMAA Certificate of Authenticity. Unlike most of the items that tend to hit eBay today, we make sure that each and every item that we offer was obtained in person, by us. While most of the autographs in our inventory are obtained in New York City, GMAA also travels to select film festivals and conventions from time to time.

Why Our Product?

While only some of our items come with “proof” pictures (that is, a photo of the person signing the item), we offer a money back guarantee that EVERY one of our items is 100% Authentic. There are many fake items on eBay, and few sellers who are as passionate about obtaining their autographs in person as we are.

Why Our Company?

GMAA prides itself on fast shipping, excellent communication, and top-of-the-line customer satisfaction. We have over 2,000 items in inventory on eBay, and dozens more that have not been listed. It is therefore extremely likely that if you are interested in an item that you do not see here, we still may have it in stock or could obtain it in the near future. Also, please use our search feature to browse our other items.

Our Goal:

Our goal is to make our customers feel as comfortable as possible when purchasing autographs. We are aware that many buyers feel a sense of doubt when purchasing autographs on eBay, therefore we do all that is possible to make buyers feel protected such as including "proof shots” and in certain circumstances "exact proof shots." This is to ensure that our customers feel as though they are getting a truly authentic piece—and with GMAA, there is no doubt that you are.

Our Third Party Authentication Guarantee:

We offer a guarantee that our autographs will pass a third party authentication test at AutographCOA (ACOA) or Beckett Authentication, or the customer will receive a 100% refund. Please contact us ahead of purchase to request this service. We are happy to submit any of our items for you, for free, with a 4-6 week added turnaround time.
