Each and every hand-signed item is witnessed by a representative of Authentic Signings, Inc. Once the item is autographed, they were individually examined for quality and signature condition. The items are then authenticated with our three step authentication process. One tamper-proof hologram has been fixed to each product, along with the certificate of authenticity and photos from the signings. Authentic Signings, Inc. guarantees each piece to be 100% authentic with a lifetime guarantee. Any alterations or damages to the article acquired shall automatically invalidate the guarantee.
