The earliest posters in the collection feature Leonora Jackson, one of the first female violinists to gain international fame, circa 1900-1915. The most recent poster is a 2020 Black Lives Matter poster. In between is everything from a 1968 Nixon/Agnew campaign poster, to Baltimore City Fair posters from the 1970s, to a poster from the U.S. Pro Cycle Championship held in Baltimore in 1982.

The bulk of the posters in the collection, over 1,000, are World War I and World War II era propaganda posters. Most were produced by the U.S. Government; the collection also consists of privately printed posters, both from the United States and abroad.
