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.
1978 LEGO Sets
In 1978, LEGO introduced several groundbreaking themes that would define the company for decades. One of the most significant developments was the expansion of the LEGO Town theme, which built upon previous city-focused sets. This year, LEGO introduced new models of public transportation, including buses and taxis, further enhancing the realism and playability of urban environments.
