We won't judge you if you find the idea of a "Museum of Miniature Books" strange. Obviously, most of people do, because this is the only one of its kind in the entire world, and it owns a certificate from the Guinness Book of Records, claiming it's the largest private collection of miniature books in the world. The smallest book in the Museum (and also ever published in world history) is just 2mm x 2mm and could be read only with a special magnifying glass.
