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.
1967 LEGO Sets
In 1967, LEGO standardized its model scale, moving from the 1:87 Town Plan format to the larger 2×2 wheel scale used in Train and Model Maker sets. This unification set the stage for the modern LEGO System and the eventual minifigure scale of the late 1970s. New innovations included black rubber tires, the first hinge elements, and LEGO’s earliest promotional tie-ins—six exclusive sets released through Kraft Velveeta. The phasing out of Town Plan and 1:87 vehicles marked the end of LEGO’s early era and the beginning of a consistent global design standard.
