Abstract
A book cover for retaining objects is presented including a front panel and back panel hingedly connected to form a book cover. A window extends outward from the front panel in the book cover, forming an enclosure for retaining objects between the cover and a surface proximate to the cover. The window can be clear, displaying the objects held in place thereby, and the book cover may include a closure mechanism to prevent the window from opening and letting the pieces out. The book cover may also be incorporated into an educational activity book comprising a front panel and a back panel connected to form a book cover. Puzzle pieces may be provided in one embodiment for inclusion in the cover of the book in order to assist in teaching children object association and enhancing their coordination.
