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.
1969 LEGO Sets
With increased international expansion and sale increases, by 1969 the number of people employed by LEGO in Billund reached 843. In 1969 LEGO revisits the pre-school block and develops the fully compatible DUPLO System. It was the basis of a complete line of toys for a market previously untapped by the company: newborns through 6 years old, however in the US Samsonite entered this market with their Jumbo Bricks in previous years. LEGO also introduced a new series of red train wheels with spokes, increasing their new train systems. 1969 brought with it numerous new sets, to date, one of the largest set releases thus far, still, the primary driver of new sets was the Trains theme.
