The Division produced 1438 designs for propaganda posters, cards buttons and cartoons in addition to 20000 "lantern pictures" (slides) to be used with the speeches. Charles Dana Gibson was America's most popular illustrator and an ardent supporter of the war. When Creel asked him to assemble a group of artists to help design posters for the government, Gibson was more than eager to help. Famous illustrators such as James Montgomery Flagg, Joseph Pennell, Louis D. Fancher, and N. C. Wyeth were brought together to produce some of World War I's most lasting images.
