LEGO Duplo / PreSchool Sets

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.
