LEGO 1973 / Universal Building Set / Basic Set Sets

The LEGO Universal Building Set Basic Sets theme, active from 1966 to 1977, provided a foundation for creative building with a variety of versatile bricks and elements. These sets were designed to encourage open-ended construction and imagination, featuring an assortment of basic bricks, plates, windows, and doors. They allowed builders to create anything from simple structures to more complex models, laying the groundwork for LEGO's emphasis on creativity and versatility. Key sets in this theme include 088 4.5V Super Set, which introduced motorized components powered by a 4.5-volt battery, enhancing the complexity and functionality of LEGO creations.

In 1973, LEGO introduced several new sets and themes, marking a significant year of innovation and expansion. One of the most notable developments was the introduction of the LEGO Town theme, which included the first minifigures with movable arms and legs. While these early figures lacked facial features and detailed printing, they represented a major step toward adding more realism and playability to LEGO sets.
