Hegi Feldstereos

Germany, 1910s

Produced by Feldstereo-Verlag, this folding cardboard viewer was designed to show scenes from the war in 3D. The text on the back translates to:

“Feldstereos are of interest to anyone in the filed or who has loved ones in the field. They reinforce the memory and convey an understanding of the tremendous events at the front.”

The design is identical to Le Bergoscope and the focus is adjustable by choosing the card slot that provides the best viewing.
