I have an old picture of Duff College (Pittsburgh, PA) Baseball team circa 1919, does anyone know the value?

This picture is from about 1915 or so, and of a baseball team. The shirts say Duff College and I ume it is from Duff College that was in Pittsburgh, Pennsylvania at the time. Does anyone know the value of such an item? I Can't find any information on Duff College on the web.
