A Building has Two Faces

About a week ago I was walking down a street (lost again), and found a building with two different faces placed at the top of every other window arch.  At first I thought they were two different people, but then upon closer examination - I think they're the same guy.  One happy face and one angry face - I wonder if this guy was the owner, builder, architect or someone else?  Time to do a little research...

What do you think?
