The tagline of this army recruitment poster from 1946, its simple, modernist design showing a gleaming rocket ship heading into the night sky, echoes the futurist theme of the 1939 New York World’s Fair, promoted as the “World of Tomorrow.” It points to both the key role played by the U.S. military in the development of the latest technologies (not least the atom bombs on Japan that had decisively ended World War II in August 1945), and the exciting, modern opportunities offered by a career in the army.
