Not real in my opinion. I went to Autograph Wax and none of the music autographs I saw looked real to me. Did you buy it in the last six months? If so you should be able to get a chargeback through your bank card. Do it now.
I don’t believe this is authentic. Someone is trying to forge his modern, rushed, abbreviated signature. Hard to believe, but this is missing the “shakiness” usually found in his recent authentic signatures. There’s a chance it’s real, but I don’t think it’s a big chance.
