Official National League (Heydler) was signed at the ballpark in Pittsburgh, during the World Series, as the most powerful squad in history murdered the Pirates. The Yankee Stars such as Ruth (5/10), Gehrig, Shocker, Ruether, Lazzeri, Moore and Pennock are here, as well as VIP's in attendance like John McGraw and George Sisler. Twenty-four signatures in all average 4 to 5/10, with all signatures listed easily legible. A great memento from a moment of singular brilliance. Includes original Spalding baseball box.
