Read this: Graphic Design in Germany: 1890-1945 (Weimar and Now: German Cultural Criticism) (Hardcover)I've always been so fascinated with how popular culture or communication (advertising) mimics the underlying subconscious of the populous. I mean, you'd think there'd be some barbershop ad in this book that will list "All Arayan since 1903" or something similar. It's amazing to me the difference in style of communication when someone is just forwarding an idea (as in an opinion piece) vs. forwarding communication designed to agree with you subconsciously with a clear drive to action (as in a piece of advertisement that implores you to buy a consumer product good).D
