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.
1960 LEGO Sets
1960 was both a turning point and a trial for LEGO. A warehouse fire destroyed most of the company’s wooden toy inventory, prompting a full shift to plastic production and the LEGO System of Play. New Basic sets debuted with distinct box artwork, replacing earlier generic packaging. LEGO Finland and LEGO Netherlands were founded, and marketing efforts expanded sharply with new advertising campaigns, solidifying LEGO’s focus on the brick as its core identity.
