The Posthorn, a publication of the Scandinavian [stamp] Collector's Club, reports in the most recent (February) issue that Finland is releasing a booklet of four stamps whose designs were chosen from 500 entries in a photo contest for "the prettiest outhouses" in Finland. More details (and purchase information for the booklets) at Posti - the website for the Finnish postal administration.
The contest was conducted to promote ingenuity and innovation in outhouse design; the 10,000 Euro prize was awarded to an entry that adapted the many knotholes in spruce as light sources and ventilation sources while preserving necessary privacy.
While briefly researching this topic last night, I discovered that the historic Hopper-Bowler-Hillstrom house in Belle Plaine, Minnesota which features a five-hole, two-story outhouse connected to the main house via a skyway; the outhouse was added in 1886 as an upgrade to the original 1871 home. The house is now open to the public; visitors may see the outhouse (but may not use it). The image embedded at right is cropped from the original.
I was going to end with that - until I found the photo of the twelve-family, three-story outhouse (the Missouri History Museum does not allow the image to be embedded.)
