July 16, 1914 RPPC of Babe Ruth on the mound at Fenway during his second ML game. This is the earliest known image of Ruth in the Majors. Here is an article about it in the June 2017 SABR Pictorial History Research Committee Newsletter if you want to know more: http://sabr.org/research/pictorial-h...ee-newsletters. And yes, the HOF made it clear they when they were assisting me with my research that they would love to have this in their collection if I am ever so inclined.
Jim, can you even put a price tag on something like this? I'm assuming you bought it first and then learned that that was Ruth on the mound (later)?
