Abstract
A frame supports stereoscopically paired pictures and a pair of lenses for viewing the pictures. The frame is foldable to vary the distance between the lenses and the pictures so that an observer can focus on the pictures in accordance with the observer's particular optical characteristics, whereby a three-dimensional picture image is viewed. The distance between the viewing lenses can be varied to accommodate variations in the distance between the eyes of different observers. The entire viewer can be folded flat for storage and shipping convenience.
