This is killer..1926 is written on the back-also dated by the jersey. 1926 is important here as it was the year of his famous strikeout in the WS of Lazzeri. This was a day after an all night "binger" after his complete game win. It even looks like he "slept" with his hat on here

GROVER led ST. LOUIS to their FIRST WORLD SERIES WIN with 2 wins and a save in the twilight of his career against the MIGHTY YANKEES. This story shows how truly talented and flawed he was. LEGENDARY
