Abstract

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.

Dependent Claim 25 words
The book of claim 1 wherein the binding means is a looseleaf mechanism permitting pages to be substituted, removed from or added to the book.
Claim 11
Dependent Claim 157 words

Claim 12
Dependent Claim 157 words
An educational book providing interaction of graphic information contained on reference elements graphic information contained on apertured leaves, said book comprising: a base leaf having a front side and back side; at least one reference element containing graphic information rotatably attached to the base leaf front side; at least one reference element containing graphic information rotatably mounted to the base leaf back side; a first plurality of apertured leaves having graphic information areas juxtaposed with respect to the apertures, said leaves in register with and overlying the base leaf front side with the apertures visually aligned with the front side mounted reference element; a second plurality of apertured leaves having graphic information areas juxtaposed with respect to the apertures, said leaves in register with and overlying the base leaf back side with the apertures visually aligned with the back side mounted reference elements; and binding means binding said apertured leaves and base leaf together at one end.
