The LEGO Duplo PreSchool theme, active in the early 1970s, was among the first Duplo lines designed for younger children. Key sets in this theme include "LEGOVille" (082), which featured a variety of buildings, vehicles, and figures to create a small town setting; "PreSchool Set" (78 and 75), which included basic building elements and figures to encourage creative play and learning; and "Train Station" (081), which provided a simple train station setup with a train, track, and station elements. These sets focused on developing fine motor skills and imaginative play in preschool-aged children.
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.
