Late husband was a disc jocky for 40+ years. he took these jeans backstage to every meet n greet to get autographed. it all started 40 something years ago when he was backstage and had nothing to sign on and all he had was his vintage levis he was wearing. im sure these are original and possibly no one else thought to do this. I have Photos of many of these autographs. backstage passed and pictures to authenticate.
