This selection of images from the World War I poster collection donated to the Museum by railroad executive and financier John W. Campbell (1880-1957) in 1943, is representative of many shown in Posters and Patriotism: Selling World War I in New York. When the United States entered World War I in April 1917, New York City's artists and illustrators were enlisted in the war effort. Many of them worked for the federal government’s new Division of Pictorial Publicity, and created these images to stir the American public to wartime loyalty, duty, and sacrifice.
