The Newman & Guardia Special Stereoscopic is a British-made stereoscopic plate camera designed to produce paired side-by-side images for stereo viewing. It dates from the early stereo-camera era and was sold as a specialist instrument for amateurs and professionals interested in three-dimensional photography.

Auction evidence for the Special Stereoscopic is very thin: a single recorded UK saleroom hammer result of £587 (Christie's, 2002) provides the only data point, so today's price ceiling and floor cannot be reliably bracketed from sales alone. As of 2026 a clean, complete example would likely sell for a similar three-figure sum at auction, though condition, completeness of the original case and plate holders, and shutter function will heavily influence what it sells for.
