I did not want to chance damaging them any further by attempting to clean them. I figured I would leave that up to an expert.The board is made of beautiful hand laid 2 tone wood tiles and has hinges to fold it in half, allowing the pieces to be stored inside. I believe this set to be from the 1920-s.
