ABSTRACT:
Disclosed is a book which includes one or more transparent sheets inserted between the pages of opaque stock. The transparent sheets have images painted, drawn, or otherwise reproduced on both sides of the transparent sheet. The images are mirrored in size and shape from front to back of the transparent sheet affording the viewer one basic image that has two different views. The present invention, when seen as a page in a book, allows illustrations or text, on opaque pages, to be altered without losing sight of the original pages.
