Babe hit three home runs in Washington in the 1918 season May 7, June 28, and June 30. In 1919, Babe hit one home run in Washington, on Sept. 27. If it can be shown that the ballpark is the Senators, and that it is 1918 or 1919, and none of the other 4 home runs that were hit in each of the two seasons by other members of the team were in Washington, then I think you have a very very strong argument that it is the Babe - as the only remaining question as to absolute certainty would be whether the picture is definitely of a home run. If we can pin the stadium picture to 1919, perhaps we can say pretty assuredly the picture is from Sept. 27, 1919.
Need to review 1915-1917 as yet, but as I think it is indeed Babe, would like others to assist first in year of ballpark image, as I bet it is 1918-1919.
