ABSTRACT:
A stereographic book includes a case having a bottom shell. The bottom shell includes a bottom surface, a front side wall, and a rear side wall. The case also includes a top shell pivotably coupled to the bottom shell adjacent the rear side wall of the bottom shell. The stereographic book also includes an optical viewer pivotably coupled to the bottom shell adjacent the front side wall. The optical viewer includes a lens system. The stereographic book further includes a plurality of pages including a first surface having imagery thereon. The pages are pivotably coupled to the bottom shell adjacent the rear side wall spaced apart from the optical viewer by a predetermined distance. Therefore, a user can pivot the pages relative to the bottom shell and view the imagery through lens system of the optical viewer. The lens system of the optical viewer has a predetermined focal length substantially equal to the predetermined distance between the pages and the optical viewer.
