The LEGO LEGOLAND theme, introduced in the 1970s and continuing into the 1980s, comprised sets that replicated everyday scenes, vehicles, and buildings in a more simplistic style than later themes. These sets, pre-dating the minifigure era, were designed to represent various aspects of life, from towns to vehicles to castles. The LEGOLAND theme was foundational in the evolution of LEGO, bridging the gap between basic brick building and the more themed, narrative-driven sets that would become standard in subsequent years.
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.
