Mickey Mantle and Yogi Berra give some superstar power to the last card in the 1957 Topps set. A toe dipped in the multi-player waters in a final series experiment, these cards would proliferate over the next dozen years. It's hard to argue with the player selection here, and the grade of PSA EX-MT 6 reveals a card that wants for centering and not much else.  There's a nice rough cut along both short edges as well.
