LEGO Duplo Building Sets consists of basic brick assortments designed for young children, featuring large, easy-to-handle pieces that encourage creativity and free play. These sets provide a foundation for early building skills with a variety of colorful bricks, doors, windows, and figures, allowing for open-ended construction. Aimed at preschoolers, the theme emphasizes simple stacking, imaginative play, and hands-on learning, making it a staple in the Duplo lineup.
1973 LEGO Sets
1973 marked major structural and product milestones for LEGO. The company ended its U.S. licensing agreement with Samsonite and established LEGO Systems, Inc. in Brookfield, Connecticut, giving LEGO direct control over its American distribution. DUPLO was formally branded as a standalone preschool line, expanding on the larger bricks first introduced in 1969. Early Town sets began to appear with simple, posable figures—precursors to the modern minifigure—bringing more life and movement to everyday scenes. LEGO’s catalog continued to grow rapidly, reinforcing its position as a leading global toy brand.
