Bat from McGwire's first full big league season bears the future single-season HR record holder's (at least for a few years) signature AND written notations verifying a specific homer he'd hit with it -- rare for a home run legend's bat. Personal model Rawlings Big Stick signature boasts his grade 8/10 signature in black marker inches from the barreltop with "H.R. #39, 8-14-87". On that day, McGwire crushed his 39th of the season against California's Don Sutton, a HOFer, en route to a rookie record 49. LOA. Splendid item of Mac memorabilia! This bat is not game used.
