Introduction

During World War I, the impact of the poster as a means of communication was greater than at any other time during history. The ability of posters to inspire, inform, and persuade combined with vibrant design trends in many of the participating countries to produce thousands of interesting visual works. As a valuable historical research resource, the posters provide multiple points of view for understanding this global conflict. As artistic works, the posters range in style from graphically vibrant works by well-known designers to anonymous broadsides (predominantly text).

The Library of Congress Prints & Photographs Division has extensive holdings of World War I era posters. Available online are approximately 1,900 posters created between 1914 and 1920. Most relate directly to the war, but some German posters date from the post-war period and illustrate events such as the rise of Bolshevism and Communism, the 1919 General Assembly election and various plebiscites.

This collection's international representation is among the strongest in any public institution. (For other major holdings, see the Related Resources page.) The majority of the posters were printed in the United States. Posters from Australia, Austria, Belgium, Canada, Germany, Great Britain, Italy, the Netherlands, and Russia are included as well. The Library acquired these posters through gift, purchase, and exchange or transfer from other government institutions, and continues to add to the collection.

World War I and the Role of the Poster

World War I began as a conflict between the Alllies (France, the United Kingdom, and Russia) and the Central Powers (Germany and Austria-Hungary). The assassination of Archduke Francis Ferdinand, the heir to the throne of Austria-Hungary and his wife Sophie ignited the war in 1914. Italy joined the Allies in 1915, followed by the United States in 1917. A ceasefire was declared at 11 AM on November 11, 1918.

The poster was a major tool for broad dissemination of information during the war. Countries on both sides of the conflict distributed posters widely to garner support, urge action, and boost morale. During World War II, a larger quantity of posters were printed, but they were no longer the primary source of information. By that time, posters shared their audience with radio and film.

Even with its late entry into the war, the United States produced more posters than any other country. Taken as a whole, the imagery in American posters is more positive than the relatively somber appearance of the German posters.

Poster Themes

The posters in the Prints and Photographs Division deal primarily with recruitment, finance, and home front issues. Although produced in different countries, many designs use symbols and messages that share a common purpose. (To explore the full array of topics and symbols supplied as index terms on individual poster descriptions, see the Subject/Format browse list.)

Enlistment and Recruitment Posters

Many posters asked men to do their duty and join the military forces. In the early years of the war, Great Britain issued a large number of recruitment posters. Prior to May of 1916, when conscription was introduced, the British army was all-volunteer. Compelling posters were an important tool in encouraging as many mean as possible to enlist. Four rarely seen posters printed in Jamaica and addressed to the men of the Bahamas illustrate the point that this war involved many parts of the world beyond the actual battlegrounds [ view Bahamas recruitment posters].

Women, who weren't being recruited for the military, were also asked to do their part. They could serve through relief organizations such as the YWCA or the Red Cross, or through government jobs. The Women's Land Army was originally a British civilian organization formed to increase agricultural production by having women work the land for farmers who were serving in the military. A Women's Land Army was also assembled in the United States.
