The Princeton University Library donated the Princeton University Poster Collection documenting World War I and World War II posters to the Smithsonian Institution in 1963 and 1967. The collection represents one of the largest and most complete collections of United States war posters produced. Help us transcribe these catalog sheets containing information about each poster in this important collection. Find instructions for transcribing these projects here . Your work will help the Archives Center staff make the collection more widely accessible through the Smithsonian’s Online Virtual Archives.
