This stunning vintage stone lithographic American Art Deco poster for war prisoner aid was created by Edward McKnight Kauffer (1890 – 1954). The poignant image of a captured GI behind barbed wire and the appeal “You Can Set Their Spirit Free” is poster making at its best. McKnight Kauffer was born in the United States, settled in England in 1914, started working in posters in 1921 and returned to New York in 1940. The framed poster measures 25” x 18”.
