The Talbot “Invisible" Camera, Nr. 206, marked “Walter Talbot Berlin" with Anastigmat f5,5 lens. The shutter works at 1/25th and uses a trigger release to trip the shutter and advance the film. The camera was worn as a belt with the lens protruding through a buttonhole. Made circa 1914-1929 in very small numbers, this belt camera also uses the then-new photographic format - 35mm roll film. Walter Talbot, a photographic dealer in Berlin, offered the camera as the “only one by which a photograph may be taken without anyone being able to tell that an exposure is being made.... where secrecy in the taking of photographs is essential." One of the most fascinating - and the most rare - Walter Talbot cameras, the only other example of the Talbot “Invisible" Camera with known whereabouts is in the collection of the Museo Nicéphore-Niépce in Chalon-sur-Saône, France. Offered in its lined suitcase with straps, this “Invisible” Camera includes the original instruction booklet in German, a hand-written letter from the renowned collector and writer Michel Auer dated July, 1980 in which he offers in excess of $15,000 for the belt camera, an Appraisal letter dated the same year, as well as an array of other literature in English.
