The collection consists of posters from both World War I and World War II with a few tourist and other miscellaneous posters from the same periods. More than half of the posters are from countries other than the United States. French posters predominate, but there are also World War I and II posters from Belgium, Canada, England, and Italy, plus World War I posters from Germany and World War II posters from Czechoslovakia, Mexico, New Zealand, Norway, and Yugoslavia. Additionally, the collection contains broadsides, banners, pamphlets, and ephemera.
The majority of the items in this collection are original pen and ink cartoons drawn for the Chicago Tribune from 1903 to 1944. These editorial cartoons focus on social issues, economics, politics, and both World Wars.
