The F.M. Richard Glyphoscope is a French stereoscopic camera for producing paired images on plates, a format popular from the late 19th into the early 20th century. It was sold as a combined stereo camera and viewer, a configuration Richard specialised in for the amateur stereo market of that era.

Auction evidence for the Glyphoscope is thin: the two UK hammer results on file are both £51, recorded at Christie's in 1998, so any sense of today's value rests on a very small and dated sample. Because these are saleroom hammer figures rather than retail asking prices, what a collector actually pays through a dealer in 2026 can be meaningfully higher, and condition of the optics, shutter and original case strongly influences what a Glyphoscope sells for.
