Here is a picture of my wife's grandfather taken during WW1. He was in the 80th Division. I have his WWI tunic which looks like the one he is wearing in this picture.
80th Division
Organization
The unit was first organized in August 1917 and activated the following September during World War I as the 80th Division. Nicknamed the "Blue Ridge Division", it was initially composed of draftees from the mid-atlantic states of Maryland, Pennsylvania, Virginia, and West Virginia.
