Mickey Mantle retired from his pinstriped day job in 1968, where he clocked in a World Series record for most home runs, as well as punching out 536 career homers as a Yankee slugging phenomenon. White threading forms the classic NY emblem on this official Yankees pro model cap, where on the brim Mickey Mantle signs (9/10) in silver pen with his “No. 7.” Under brim contains an Upper Deck hologram, and cap is NRMT. On back in silver pen is “49/536”, signifying the 49th of 536 (Mantle’s number of career home runs) caps signed.
