Abstract
Abstract A viewer is constructed of an inexpensive material such as paper and is designed to be disposed of after minimum usage. The viewer is constructed of a blank of paper foldable to form a base or handle portion, a viewing portion, and a face portion on which advertising material may be carried. The viewer has a magnifying lens and has means for movably receiving slides viewable through the lens when the viewer is unfolded. By means of a novel arrangement of panels and fold lines associated therewith the viewer can be folded into a flat package for shipment or storage.
