The “Advertisements and promotional materials” series are predominantly posters, some original artwork, calendars and photographs which date from the 1880s through to the 1950s. In the “DuPont Company” subseries are primarily advertisements for powder which either emphasize the military uses or hunting and rifle trapshooting. The hunting posters often are of game birds or hunting dogs or of men and boys hunting. The Trapshooting posters generally show men and women shooting rifles or highlight contest trophies or winners. There are a few advertisements for other products such as Rayon, Cellophane, and Pyralin.

The “DuPont Company subsidiaries” subseries are mostly poster advertisements, some smaller prints and photographs. Although there are materials from seventeen companies in the subseries, only two companies have multiple items Laflin & Rand and Harrison Brothers & Co.
