These are the basic brick sets sold in North America by Samsonite, the luggage maker, which held the LEGO licence there from 1961. Samsonite made the ordinary bricks itself, first at its factory in Stratford, Ontario, while the special parts came over from Billund, and in 1965 it opened a plant in Loveland, Colorado, used only for LEGO.
1962 LEGO Sets
In 1962, LEGO introduced one of its most important innovations—the wheel. This addition transformed LEGO from a static building toy into a dynamic system of movement. The first wheel sets (400 and 401) featured plastic hubs with rubber tires, enabling realistic vehicles and construction models. The company also expanded globally into Asia, Africa, and Australia, and established a process development lab in Billund that pioneered the switch to ABS plastic, which became standard the following year.
