Abstract: An educational book providing interaction between graphic information contained on reference elements rotatably attached to a base leaf and a second set of graphic information contained on apertured leaves. The apertured leaves superimpose the base leaf and reference elements, such that the apertures are visually aligned with the reference elements. The second set of graphic information areas are juxtaposed with respect to the apertures of the leaves to combined with the graphic information of the reference elements visible through said apertures. To maintain this alignment, the apertured leaves and base leaf are rotatably bound together at one end by a binding mechanism.
