A metal construction set made in Bogotá by the Franco-Colombiana Christian Le Paliscot factory. Its strips, axles, gears, pulleys, wheels, screws and nuts could be assembled and taken apart to make models, many of them movable; the leaflet for box No. 1 advertised more than one hundred possible constructions. The Colombian Pedagogical Museum connects its use with hands-on learning about mechanical principles and basic physics and mathematics.
