Did you get this item signed in person? or purchased it? Unfortunately items like this are so hard to authenticate b/c of the way the marker bleeds into the fabric, especially this fleece type material. Even when signatures look good on items like this, i know i could be fooled very easy b/c of the fabric. But hey, if your somewhere and see the stones and have nothing else for them to sign, then id use whatever material i could find..........and like it. lol
