About LEGO Classic Supplemental
Supplemental sets are the parts packs of the 1960s, sold so that builders could add to a basic set the bits they needed most. They held windows and doors in frames, plates in several sizes, corner bricks, gates and fences, turntables, wheels with axles and train couplers. Many of these parts were new at the time, and the packs were often the first way to get them, like the wheels LEGO introduced in 1962.
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.
