Tessina camera made by Concava in Switzerland from 1956 to 1966.

A subminiature camera for 35mm film loaded into special cassettes. The Tessina took 35mm film which ran horizontally through the camera. A mirror behind the lens reflected the image on to the film. A second lens, coupled to the taking lens, produced an image on a reflex focusing screen, fitted with a folding hood which incorporated an optical frame viewfinder. The Tessina was small enough to be worn on the wrist - a detachable strap was supplied for this purpose.
