How lucky can No. 7 be? When Mickey Mantle signs his name with his number on both a bat and a Yankees jersey, plenty lucky for anyone who gets them. Readily identifiable autograph in black marker is written under the Yankees' interlocked NY in a limited-edition 1951 replica jersey with the American League's Golden Anniversary patch of crossed bats on the left sleeve. Mantle's inscription on a reissue of his original Louisville Slugger is under his branded signature. A jersey, a bat, The Mick on both. How could you go wrong?
