Consul, The Educated Monkey is an educational toy that performs small multiplications. If you point the monkey's feet at two numbers, its fingers point to their product. To multiply a number by itself the second foot should point to the square symbol. This is a replica, but it was originally produced from 1916 to the early twenties. It is named after a real animal that performed on stage at the time.
