The G.A. Krauss Stereoplast is an early 20th-century French stereo camera, designed to expose paired images for stereoscopic viewing. It belongs to the era when stereo photography was a mainstream amateur format, and Krauss of Paris produced a range of plate and stereo cameras for that market.

Evidence of what a Stereoplast is worth in today's market is thin: the only documented UK auction hammer result on file is a single 2007 sale at £84, which sets a wholesale data point rather than a reliable range. With just one record, the price a Stereoplast sells for in 2026 will depend heavily on completeness, lens condition and whether the original case and plate holders are present, so buyers should treat that figure as indicative only.
