  • Patent number: 4931017
    Abstract: A book for children comprises a front cover, a back cover and a plurality of sheets forming a succession of pages between the front cover and the back cover. The sheets are die cut or perforated to form knockout plugs intended to be removed by the consumer. When the plugs are removed, the sheets form a stencil and define a work page bearing an illustration related to the stencil. A tutorial page adjacent to the work page and visible together with the work page when the book is opened to the work page illustrates the appearance of an image when properly drawn with the aid of the stencil. A binding for the covers and sheets enables the book to be opened to any of the pages and to lie with both of the covers and all of the pages flat. This facilitates the use of the book as a stencil book.
