I got you a special one, Jim. Not everyone knows this, but back in 1947, the Mapes was not on a sewer system. They used a large brick septic tank. Your brick is about an FU42. It's exceedingly rare. I'd scan it for you, but my wife won't let it in the house because of the smell. Just imagine the history... I'm sure all the big stars that stayed there used the facilities!
