In my mind I have a picture of a classic "Old School" outhouse, but funny thing is that I am having trouble finding a picture of it. This is about as close as I can find. A classic outhouse should have a slant roof, simple, unpainted vertical boards making up the body of the structure, and some sort of vent in the roof. This picture has those characteristics. In my mind though, the outhouse should have a vent cut in the side that is a moon shape and then beside it a star. Don't know how that got started, but many outhouses have moons and stars cut through the wood for ventilation. Also, in the back there should be a hinged door to enable easy cleaning.
