The Fleury-Hermagis Stereo is a French-made stereoscopic camera, designed to expose paired images for binocular viewing. Fleury-Hermagis was a Paris optical maker active in the 19th century, and stereo cameras of this lineage typically date to the wet-plate or early dry-plate era.

Sales data for this model is extremely thin: a single recorded UK auction hammer result of £6,000 in June 2015 is the only data point available, so a meaningful price range cannot be established. With one sale on file, the value of a Fleury-Hermagis Stereo today is best confirmed by reviewing comparable saleroom results at the time of consignment rather than relying on a published median.
