Unused Washington News Company card, whose caption says “at 200 by 400 feet, is the largest brick building in the world”.  It’s funny.  If you go to Google now to see what the web considers to be the largest brick building, you will come away thoroughly confused.  Malbork Castle, built 800 years ago?  Cathedrale Ste-Cecile in France?  (If the postcard says so, it must have been true.  Right?)  Grade: 1
