In 1987, Mark McGwire announced his arrival in the major leagues with a rookie season so overwhelming that he became the unanimous winner of the American League Rookie of the Year Award. He clubbed 49 home runs in his first full season with the Oakland Athletics, a figure that stood as the MLB rookie home run record for decades and launched one of the most feared power careers in baseball history. This Pillbox Bat Company Mural Series Bat features McGwire's hand-signed autograph and the "1987 AL ROY" inscription, tying the piece directly to the award that first put his name on baseball's radar. Numbered 1 of 5, this is the first in an extremely limited run, making it a premier acquisition for any collector of Athletics history.
