San Francisco Street Sighting - 1952 Citroën 11CV Traction Avant

Every once in a while a car comes along that I genuinely don't know much about at all. I research the heck out of it to try to determine what it is. Usually it's an obscure European model that wasn't changed much during a long production run. Sometimes it's a car that was rare to start with in the American market and is only more rare now. And sometimes it's French.
