Double-Header retail baseball signed in black felt-tip pen by twenty-six members of the 1966 Pittsburgh Pirates, including Clemente, Stargell, Mazeroski, Alou (sweet spot), Pesky (coach; sweet spot), Law, Pagan, Cardwell, Michael, Bailey, Alley, Hoak (announcer; ball label), Smith (coach), Rodgers, Fryman, Lynch, Veale, May, King (coach), O'Dell, Sisk, Blass, and Grammas (coach). Signatures average 8/10. This ball comes with the special provenance of having been obtained personally by our consignor in 1966. As a boy, he used to stake out the New York hotels for the visiting ball clubs and obtain the signatures of the players in the lobby. This is one of many team balls in his collection that was obtained in that manner. Excellent condition overall. Full LOA from PSA.
