A historic piece of baseball memorabilia: the original game ticket from Roger Clemens' legendary April 29; 1986 performance at Fenway Park; when he struck out 20 batters in a single game--an AL record that stood for 20 years. This ticket is hand-signed by Clemens with the inscription "20Ks;" commemorating his record-breaking achievement. Authenticated and graded PSA 10 auto grade; this is one of the most significant pieces from one of baseball's greatest pitching performances. A must-have for serious Red Sox and Clemens collectors.
