The 1971 World Series matched the defending champion Baltimore Orioles against the Pittsburgh Pirates, with the Pirates winning the Series. The two teams proved to be evenly matched, as the Series went the full seven games, with the Pirates' Steve Blass pitching a complete game four-hitter in winning Game 7, 2–1, against Mike Cuellar and the Orioles. The Pirates' Roberto Clemente, who turned into a one-man gang in the Series, became the first Spanish-speaking ballplayer to earn World Series MVP honors. Clemente hit safely in all seven games of the Series, including 2 home runs.

This lot includes two 1971 World Series programs. One from Baltimore and the other being from Pittsburgh. Both programs are in excellent condition with no rips or creases.
