Hehe, this is not museum, but my toilet (which is a dry toilet outdoors). I don't know if this is universal, but at least here in Finland we have a habit of decorating the outdoor toilet walls with old posters, magazine covers, postcards etc. So, in a way, a small-scale art exhibition to remind one of all the beauty and joy in the world =)

Here we see a postcard I once got from Russian friends. The colourful picture is by an artist called Sanni Stella.
