The digital collection World War One Posters has been created by the Library Company of Philadelphia. This collection contains some 300 posters created in the United States between 1913 and 1922. You can browse the posters and sort them by date, creator or title. You can use a free text search field to search for particular posters. They can be presented in a grid form or in a list.
The World War One Collection of the Library Company contains also a relatively small number of photographs and ephemera.
