The picture below was taken at my cousin's house in Albany NY. The house is an older one, but I'm not sure of the exact vintage. To the right of the TP holder there is a mystery tile that we can't figure out what it is for. It has a shelf at the bottom and there is a vertical divider which makes two cubbies, the one on the left is smaller than the one on the right. There is also a slot at the top about the size of a book of matches. Is there anyone out there who has seen this before, and knows what its function is?
