The Voigtländer & Sohn Stereo Folding is an early stereoscopic folding plate camera, designed to expose paired side-by-side images for stereo viewing. It dates from the era when Voigtländer & Sohn — the firm's pre-merger name — produced wood-and-leather folding apparatus aimed at amateur and serious enthusiast stereo photographers.

Sales data for this model is extremely thin: a single Christie's UK auction record from 1998 shows a hammer price of £402, and no recent results are available to establish what the camera is worth in today's market. With only one historic saleroom result on file, any current value estimate would be speculative, and collectors should treat that figure as a dated reference rather than a guide to what the camera sells for now.
