Graphoscope

A graphoscope was a 19th-century device used in parlors in order to enhance the viewing of photographs and text.

The graphoscope is supposed to be based on a 1864 patent of Charles John Rowsell.

[1] These novelty items consisted of a single magnifying glass, often in a wooden frame, in an overall construction that could collapse into a compact rectangular form.

A KOMBI camera often had included in its design a graphoscope for better film viewing.

Many devices combined a Stereoscope and Graphoscope.
