This is a truly useful bathroom-stall door:

When you walk in, the sheaf of paper and books you probably have in your arms goes into the hayrack, and then your bag onto the intermediate hook, and a coat (and hat, even) onto the top hook. They've been useful for about a hundred years now. The building as a whole needs an overhaul, and I hope these subtle perfections of the old days will not be lost.
So wrote clew in Meta.
