There are so very many things I don’t know.  I just found out another of those things this week (I should have been able to put it together years ago, as I was in possession of all the pieces of the puzzle, but sometimes the obvious eludes my Dilettantish brain).
What common thread do Hubbard Hall at Bowdoin College, in Brunswick, Maine, and the Metropolitan Museum in New York share (aside from symmetrical facades?)

The answer is to be found in an upcoming post, if none of you sharp witted folk come up with it before then. There is no prize for correct answers to this quiz, aside from the satisfaction of being smarter than I am.
