Hall of Fame outfielder Roberto Clemente is the focal point of this magnificent single-signed circa 1952-57 Official National League (Giles) baseball. Signed on a side panel by the 12-time All-Star in flowing blue ballpoint ink, it is personalized "To Rickey Bruce, Best Wishes, Roberto Clemente." The Pride of Puerto Rico, Roberto became the first Latin American and Caribbean player inducted into the Hall in 1973, months after his untimely death while on a relief mission to earthquake survivors in Nicaragua. The autograph is a perfect 10/10, as graded by PSA, with an overall grade of PSA MINT 9.
