This 1964 Pittsburgh Pirates ONL baseball features 18 signatures, headlined by Hall of Famer and humanitarian Roberto Clemente on the north panel. Graded PSA 8 NM-MT, it includes other notables like Willie Stargell, Bill Virdon, and Steve Blass. The sweet spot features a genuine signature of manager Danny Murtaugh, a rare find as most examples are clubhouse signatures. Collected by our consignor as a young fan in 1964, this ball represents both a cherished memory and a truly rare opportunity to own an authentic, high-grade team ball from a legendary Pirates squad and anchored by the iconic Clemente.
