These are two different versions of “Tek” wood puzzles. They are designed to look like books and when opened there are compartments that hold a small puzzle. The smaller book holds two puzzles and measures 8.25″ x 11.75″. The larger book has four puzzles and measures 11″ x 11.75″. It is model #753. When the cover is opened there is a picture sheet with each puzzle and then the puzzles in their compartments. All of the puzzles that I have seen are Mother Goose tales.
