Basic Sets or Universal sets were part of the LEGO Basic theme, which began in the 1970s, was designed to be a more general, non-thematic series of sets. Unlike the themed sets that revolve around specific stories, characters, or concepts (e.g., space, city, or pirates), the Basic theme provided a collection of standard LEGO bricks and pieces, often in a variety of colors. The goal was to encourage free building and creativity without the confines of a specific theme or narrative.
1981 LEGO Sets
In 1981, LEGO continued to expand its thematic range to cater to a growing and diverse audience. This year saw the continued development of LEGO Fabuland, a theme introduced in 1979 and designed for younger builders transitioning from DUPLO to standard LEGO bricks. Fabuland sets featured unique anthropomorphic animal characters, simple yet detailed builds, and a strong storytelling element, blending town and country life in a way that encouraged imaginative play.
