Subminiature camera for 20 exposures on 8mm film. Built in bakelite, it is semicircular setting a target in the middle of the curvature. Its shape and its opening as small cap resembles a pill box. The camera was sold inside of a soft leather case closed by a snap and was accompanied by an instruction booklet for loading and handling. Collector's item, highly sought after rare and difficult. I believe they were made in Madrid in the 40s, and became very few.
