1981 LEGO Sets
In 1981, LEGO continued to expand its thematic range to cater to the diverse interests of its global audience. This year saw the introduction of the LEGO Fabuland theme, designed for younger builders transitioning from DUPLO to regular-sized LEGO bricks. The Fabuland sets stood out due to their unique anthropomorphic animal characters and simple builds, offering stories that blended town and country life. Alongside this, the established Town and Space themes received new additions, bolstering LEGO's offering for fans of those lines.
