Abstract
Abstract A foldable viewer is disclosed herein for presenting a graphic scene, message or the like which includes a square blank sheet of pliable material having a viewing area defined on a selected one of its surface for carrying suitable graphic or display subject matter intended to be viewed by the user. In one form, the viewing area is defined by a pair of outlined bands arranged normal to each other having opposite ends of the bands terminating at the respective adjacent edges of the square blank sheet material. Construction of the viewer is accomplished by folding selected and predetermined portions of the blank sheet over upon itself to construct an enclosure with an opening at one end for viewing the interior thereof and for particularly viewing the graphic or message material carried on the interior viewing areas.
