Grandpa's trunk - one of the smallest books in the world

When I bought it, it was advertised as the world's smallest book, but since then smaller books appeared. Anyway, it's a little wonder. This book, sold at the Gutemberg Museum in Mainz, birthplace of the inventor of movable types (and if you thought Gutemberg was born in Moguntia, you are right too: Mainz is the German name of the Roman Moguntia), contains the Lord's Prayer in seven languages: American and British English, German, French, Spanish, Dutch and Swedish. The pages are 3.5 x 3.5 mm in size, and it is bound with a leather cover...
This was a good test for my Canon's super-macro feature...
