The Delaware Postcard Collection comprises over 2,000 historic images depicting places and life in Delaware. Digital images are available through an online database, a project that was funded by the Unidel Foundation. Images can be searched by geographic location or subject terms, yielding visual sources related to African Americans such as the Colored School in Marshallton or numerous Methodist Episcopal churches throughout the state.
The Gregory C. Wilson Post Card Collection of African-American postcards and trade cards comprises 1.3 linear feet of postcards, trade cards, printed ephemera, and letters. The majority of the collection consists of nineteenth- and twentieth-century American postcards and trade cards that feature a diverse array of positive and negative images of African Americans. The collection as a whole documents the history of harmful stereotypes that represented social values and mores across the country. Images include ridicule of black religion, harm to black children, scatological humor, poverty, crime, music, and labor, as well as race relations, military service, domestic scenes, transportation, women, and tribal depictions.
