Abstract
The disclosure relates to a story book wherein the rear cover is of increased thickness so that it can hold the necessary transparencies and optics therein for viewing and wherein predetermined pages of the story book are provided with apertures aligned with transparencies and optics associated therewith so that the viewer can observe the scene being depicted on a transparency by locking through the aperture on the page. The transparency illustrations which are disposed in the book rear cover, in one embodiment, are encased in opaque tubes, each tube being aligned with one of the apertures on the book pages. Each of the tubes includes a magnifying lens on the side of the rear cover closest the apertures on the pages and a transparency of the scene to be depicted between the lens and the portion of the rear cover remote from the apertures. A transparent, translucent or frosted screen can be provided on the side of the transparency remote from the lens to permit the entry of diffused ambient light through the transparency and also to protect the transparency from outer elements. In a second embodiment of the invention, the fixed transparency is replaced by a film reel rotatable by means of a crank so that a plurality of scenes can be observed through each aperture of the book.
