Charcoal and watercolor sketch on white paper, mounted on thick paper. Sketch shows Mobile Hospital No. 39, The Yale Unit, near Chaillons in the St. Mihiel Sector of France. The hospital is made up of lots of large red or white tents. It has an access road (seen on the right), and there are two soldiers walking on it towards the compound. There is a fence in front of the hospital, trees in the background to the left, and fields in the back on the right.
