The Gaumont Spido (Jumelle) is an early stereo-style box camera produced by the French maker Gaumont, built in the binocular-form 'jumelle' layout that was common around the turn of the twentieth century. Cameras of this pattern were aimed at amateur photographers wanting a compact, hand-held plate camera at a time when most equipment was still tripod-bound.

Auction data for the Spido (Jumelle) is thin: only a single hammer result is on record, a UK saleroom sale at £250 in January 2024, so today's market value can only be anchored to that one wholesale auction price rather than a true range. Because this is a hammer figure, what a buyer actually pays at auction will be higher once buyer's premium is added, and dealer retail asking prices in 2026 typically sit above this level. With so few comparables, condition, completeness of plate holders, and originality of the leather covering will swing what any individual example is worth.
