Historic 1918 World Series Final Game - Game Used Baseball. Used in Game 6 on September 11, 1918. This was the last World Series win for the Boston Red Sox for the next 80+ years. Signed by Game 6 Pitcher George Lefty Tyler. He was the losing pitcher for the Chicago Cubs. He pitched two games in the Series. He inscribed the ball "World Series 1918" and also inscribed the box scores of a few of the games. A truly incredible piece of Baseball History.
