Here's the whole photo. The newspaper in question is at bottom right.
I believe this configuration of signage in left field is from 1910, and I'm fairly certain it can be narrowed further using the Bushmills ad specifically. There are photos of the Polo Grounds showing this ad in a different color scheme in April 1910...and then other photos, from August 1910, with the ad exactly as it is in the photo I posted. Which should place the newspaper and game around mid-September through early October (end of Giants season), given the seasonal shift to bowlers.
