Special Collections and Rare Books recently contributed several World War I posters to the Missouri Over There digitization project. Coordinated by the Missouri State Library, the Missouri Over There project explores the state's involvement in the first World War. The posters selected for digitization deal with military recruiting and home front efforts such as food conservation, savings programs, and civic organizations. Many pertain to the St. Louis area, but a few are specific to Columbia and mid-Missouri.
Take a look at the project blog, and browse the entire selection of posters in the Missouri Digital Heritage database. Special Collections has a collection of over 900 World War I posters, including examples from France, Germany, and Belgium. You can find a description of the entire World War I poster collection on the Special Collections website.
