In 1971, the Pittsburgh Pirates dedicated their first full season at Three Rivers Stadium in style, capturing the World Series title. This official National League (Feeney) ball contains 27 signatures from that team, including Clemente, Stargell, Mazeroski, Murtagh, Oliver and many more, none of which are clubhouse sigs. What truly stands out is the condition of this offering, as the ball is in NRMT condition and the autographs rate on average 8/10. A great addition to the collection of any Buccos fan.
