Produced in the 1950s by Graflex, Inc. of Rochester, New York, whose roots go back to 1887., the Stereo Graphic Viewer was the companion viewer to the Stereo Graphic Camera.

The Stereo Graphic Stereo Slide viewer accommodates 5 Perf (Realist American format) slides, or smaller image pairs in the standard slide mount .

The Stereo Graphic Viewer is internally lit, (two D Cell batteries [not included]), focusing, with two single element lenses.

With the lens separation of the Stereo Graphic Viewer the standard 2-1 2 , interocular adjustment apparatus is absent, significantly reducing production costs, so that the viewer could be economically priced to match the economically produced and priced Stereo Graphic Camera. But the color, ease of use and feel, has kept this economically priced viewer right up in desirability with higher priced single element lens stereo viewers.

Viewer is fully functioning and comes complete with colorful Original Box.
