The Book Box
carved wooden box with metal hinges
15 cm x 12 cm x 6 cm
What is inside of a book?
Paper, of course! And so the five pieces of this puzzle comprise the five "pages" of the book. They are made of homemade recycled paper and are thick, to fill the box. There are projections from either side of the page in three various shapes that must fit together. A close-up of one "page" is shown below because the patterns can't be seen in the picture above.
There is only one solution to the puzzle, which is more difficult to find than one might think.
