This vintage overcoat was made in the 1940s by Jess Butz, on the U of P Campus, 3403 Walnut St., Philadelphia, PA. It appears to have been an army private purchase piece, made of relatively lightweight wool in an olive drab shade. It is a fly front single breasted overcoat. The lining is pretty shredded and the coat is badly wrinkled. There is mothing throughout.
