Antique Wooden Stereoscopic Viewfinder in Working Condition. France, Circa 1900

This stunning device is a turn-of-the-century stereoscopic viewer, in very good condition and in working order. The viewer was made in France and has mahogany wooden box, with the surface in excellent condition and a delicate satin finish that provides it with protection and glow. The two lenses are original from the period: the eyepieces that contain them are made of black bakelite and the magnification glasses are antique too. The rear translucent glass is also the original one; it is attached to the front side of the viewer and lets the light in so the user can watch the plates properly. Stereoscopy is known since centuries ago, but it was only in the early 19th century when Sir Charles Wheatstone manufactured the first viewer. Nevertheless, in the 16th century some devices were made that let people watch images with a certain depth. During the 19th century many stereoscopic viewers (also called stereoscopes) were manufactured, and during the first half of the 20th century they became very popular instruments. In fact, they were commonly used until the 1970s. The viewer that we can see in the images stands out for its sober and elegant design, as functional as simple. The wooden box has two eyepieces with their respective lenses that make it possible to watch the plates inserted in the viewer. In order to fit them, the box has s side groove. At the top of the viewer there is a folding hatch with an inner mirror that provides the necessary light to appreciate every detail of each image. Between the eyepieces there is an oval metal plate with the brand name: UNIS FRANCE STEREOSCOPES MATTEY PARIS. The ancient age and delicate look of this turn-of-the-century viewer turn it into a first-class article with a timeless and undeniable attractive.
