During World War II Bradbury Thompson, like many other designers, worked for the Office of War Information (OWI). Among his tasks was the design of U.S.A., a magazine aimed at Americans and allies (including the Arabic and French editions shown below), as well as the occasional enemy too. The U.S. government produced a lot of low and high-impact propaganda. U.S.A. fell somewhere in between, classically designed while vociferously propagating American values.
