Steven Seidman, associate professor and chair of the Department of Strategic Communication, examines the roles that posters have played in election campaigns as a medium of propaganda in an article entitled, "Studying Election Campaign Posters and Propaganda: What Can We Learn?" published in the International Journal of Instructional Media.
According to Seidman, "By studying election posters, we can better understand how propaganda has been used to influence public opinion and how messages are designed for audiences. Such posters also can be a valuable resource for teachers and students who study history, politics, and media."
The article traces the history of political posters over 500 years, from the Protestant reformation through the current involvement of the advertising industry, and includes 10 illustrations of election campaign posters.
