Extraordinary high-grade example of Roberto Clemente's card from the 1964 Topps Stand-Up issue, the first Topps cards to be die-cut since 1951.  Since the cards were perforated and intended to be folded so the players would "stand up," they are extremely difficult to find in higher grades.  In addition, the green and yellow backgrounds are susceptible to chipping, particularly along the edges of the cards.
