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.
1963 LEGO Sets
1963 was pivotal for material and design innovation. LEGO completed its transition from cellulose acetate to acrylonitrile butadiene styrene (ABS), improving color stability, durability, and clutch power. The company also launched Modulex—a smaller, precision-scaled building system for architects—produced by the new subsidiary Modulex A/S. Modulex elements were based on a 5mm grid and designed for 1:20 scale modeling, expanding LEGO’s presence into professional design and planning.
