A toy automaton that makes drawings when cranked. An interchangeable double-cam in the base controls the vertical and horizontal displacement of the pencil. At least 24 cams were available, producing drawings that include a man with a parrot, a monkey, Napoleon and Queen Victoria. This one draws a rooster. These were a gift given only to especially good Vielmetter customers. The patent may have been purchased from the English inventor and toy maker James Walker, who 15 years earlier manufactured a similar automaton using an identical mechanism.
