The former big league lefty signed my two cards in about a month - it looks like tried to mimic his facsimile autograph on the 1971 Topps.
He sent my letter back as well, writing that he just got a callus on his left index finger and as response to the 'I hope you are doing well' I add to the end of my requests - he wrote no he isn't doing well, "my left calf is [broken]."
