A unique game used relic from one legend to another, offered here is a 1993 Oakland Athletics white home jersey (size 48 +1" sleeve length) that was worn by none other than "Big Mac" himself, Mark McGwire, during the 1993 season. The jersey shows solid usage including perspiration staining and some soiling. Gifted during the season to fellow legend-in-the-making Shaquille O'Neal, McGwire has signed and inscribed on the back in black felt tip marker, "To Shaq, the best to you on a Hall of Fame career, Mark McGwire." This jersey sources direct from Shaquille O'Neal himself and was prominently displayed in Shaq's Orlando, FL house for several decades. Accompanied by a myriad of provenance, including a Letter of Authenticity from Sports Investors Authentication to verify game usage; a Letter of Provenance signed by Shaquille O'Neal; and a Letter of Authenticity for the autograph on the jersey from Beckett Authentication Services (BAS).
