I purchased this autographed Michael J. Fox signature from Celebrity Authentics. There is a Certificate of Authenticity card from when the signature was signed. I have kept it stored without displaying it since I purchased it, so the condition is very good. Please refrain from price negotiations. Thank you to those who are interested. #Hollywood #Autograph #BackToTheFuture #ComicCon #SWAU #CelebrityAuthentics #BTTF
