Observation binoculars - 1900-2000, 1900-1910 - France - Iris

charming pair of antique French binoculars produced under the "Cycliste" trademark by the Iris de Paris maker, dating from the early 1900s to 1910s — the golden age of French optical craftsmanship, when small workshops in Paris produced field and opera glasses for the growing leisure and sporting classes. The bicycle motif engraved on one eyepiece barrel reflects the era's enthusiasm for cycling, a hugely popular pastime in Belle Époque France, while the opposing barrel bears the maker's mark "Marque Iris de Paris, Qualité Garantie."
Construction & materials
The body is finished in black lacquered metal with pebbled dark leather (shagreen-style) grip sections on the objective barrels, and a central rack-and-pinion focusing wheel. The optics remain clear and the mechanism moves smoothly, in full working order.
Case
Housed in its original French tan leather case, oval in profile, hand-stitched with a contrast cream thread and stamped "Étui Tout Cuir Favori, Déposé" (genuine leather, registered design) on the base. The case closes with its original leather strap-and-buckle closure and retains its full-length leather shoulder strap.
Condition
Excellent for age — fully functional optics, tight and smooth focusing mechanism, no cracks or splits to the leatherwork. Some light surface wear, patina, and minor scuffing to the leather consistent with honest age (see photos), which only adds to its charm and authenticity.
