This autographed Perez Steele Limited Edition postcard has been personally hand-signed by Carl Yastrzemski of the Boston Red Sox. Yastrzemski enjoyed his best season in 1967, when he won the American League Triple Crown with a .326 batting average, 44 home runs (tied with Harmon Killebrew) and 121 RBIs. Yastrzemski's Triple Crown win in 1967 was the last time a major league hitter won the Batting Triple Crown until Miguel Cabrera in the 2012 season (conversely, six different pitchers have since won the pitchers' version). He was voted Most Valuable Player almost unanimously (one voter chose Cesar Tovar of the Twins) This autograph is certified by James Spence Authentication (JSA). It comes with the numbered hologram and matching Certificate of Authenticity.
