LEGO Supplementaries were sets released during the early days of the LEGO system. These sets were designed to supplement and expand upon the building possibilities of existing LEGO sets. Instead of being complete stand-alone models or kits, Supplementaries provided additional bricks, special parts, wheels, windows, doors, gears, or even motors. These sets were especially useful during an era when LEGO's product line was simpler and less specialized than it is today.
1976 LEGO Sets
In 1976, LEGO continued expanding its product lineup with new sets and themes. One notable introduction was the LEGO Police theme, which featured police cars, motorcycles, and police stations, further developing the town and city-based play experience.
