Well, the Exeter listing does say he is from Philly... That has him in the Class of 1913 graduating but other sources say 1915. These days it's a High School but maybe they were a college then?
There is a 1915 yearbook for sale on etsy:

I asked if he was in the yearbook being sold and got the following response:

Sorry. Don't see him in the book.

Hello,
In 1915, George B Batten should have been a senior but I'm not sure he graduated or dropped out. Is he shown as a senior (with picture) in the 1915 yearbook that is offered for sale?
