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.
1975 LEGO Sets
1975 expanded Basic Building Sets and introduced more systematic, idea-led boxes. Proto-minifigures—small, faceless figures with single-piece legs—appeared in town and train sets, foreshadowing the 1978 minifigure. LEGOLAND-branded sets emphasized construction vehicles and realistic machinery, reinforcing everyday play before the arrival of dedicated Space and Castle themes.
