Tinplate Monkey Calculator

A wonderfully eccentric piece of retro novelty, this monkey calculator combines vintage fairground graphics with a clever mechanical design, using the monkey’s movable limbs to reveal the answers. A playful curiosity that brings a little old-fashioned ingenuity and theatrical charm to a desk or study. Its original design dates to 1916, making this ingenious little mathematical toy a delightful marriage of early mechanical ingenuity and playful design. Diameter 15 cm.
