Showcases convey messages and serve as intermediaries between products and passing pedestrians. While selling has remained the focus from a Western, capitalist perspective to this day, the former GDR had its own system-compliant advertising theory. In her work, the author examines, through the Berlin photo collection of the Association of German Consumer Cooperatives, the role that the showcase played as a potential communication tool in the GDR, how the design of the VDK showcases changed during the forty-year existence of the GDR, and to what extent it adhered to or deviated from socialist guidelines. The book is aimed at communication scientists, historians, cultural scholars, and anyone interested in the history of the GDR.
