For the next few weeks, I'll be participating in a MOOC (massive open online course) from the University of Nottingham in Britain. The subject is Propaganda and Ideology in Everyday Life. Let's see what these academics come up with; if this proves interesting to me, I'll comment here.
Meanwhile here are some examples of street propaganda from one of the precincts I've photographed for Walking San Francisco. Click on any of these images to enlarge.
