This episode is about wallpaper. It is an examination of why interior decoration is such a fundamental human drive and what it is evolutions says about societies throughout the ages. My very first guest is Robert M. Kelly who has been working with wallpaper as a paperhanger, researcher, consultant, and writer since 1976. In this conversation Robert walks me through the fundamentals of wallpaper scholarship, what it means for wallpaper to be meaningful and how wallpaper often acts as a material representation of our values and beliefs.
