I was probably trying to get a shot of Joan and missed the timing, but the German material about cameras on the wall is priceless, and also identifies what class this is (9th grade German, with Herr Chung). I can't make out much of the picture display, but the heading clearly says "alt und new" ("Old and new"). Other shots of the room show it's set up as a science room -- there are sinks and things up front. Maybe it was used for two things? Because I think there was only one German class a day.
