A certificate is matched with a sticker placed on the autographed item and entered into they're data base which you can search on their web site. Ive been in business for over 20 years. All autographs in my store are 100% authentic hand signed by the person, no fakes or reprints.
I travel around the country and attend private signings. Make sure to follow my store I'm constantly updating and adding new items and love to work with repeat buyers and give them deals.
