About LEGO Universal Building Set Supplemental

The LEGO Universal Building Set Supplemental theme, active from 1969 to 1976, offered additional elements to enhance and expand basic LEGO sets. Key sets include 990-2 Trees and Signs and its earlier variant 990 Trees and Signs, which provided decorative elements to add realism to LEGO creations. The 797 2 Large Baseplates Grey/White set offered foundational pieces for building larger and more stable structures. The 103 4.5V Motor Set with Rubber Tracks introduced motorized movement, allowing builders to create moving vehicles and machines.
1971 LEGO Sets
In 1971, LEGO expanded specifically to the girls market. While in the past LEGO marketed all of its models to both boys and girls alike, it was not until 1971 that LEGO produced furniture pieces and dollhouses for girls specifically. LEGO also continued to produce new sets for the Italian Minitalia brand as well as introduce new parts such as the 1x8x2 arch bricks which were first introduced that year.
