Building Sets are the plain DUPLO brick sets, buckets and boxes of bricks without a story. DUPLO started in 1969, and the name comes from the Latin word for double, because each brick is twice as long, wide and high as a LEGO brick. The studs are made to fit, so DUPLO and LEGO bricks lock together and a builder can move from one to the other. For years the plastic bucket was the usual way to sell them, from the 1980s through the early 2000s, often shaped or printed as an animal, a farm or a circus, and some came as anniversary editions. Later sets switched to cardboard brick boxes with ideas for what to build on the side.
1989 LEGO Sets
1989 was a landmark year with the global debut of LEGO Pirates, introducing expressive minifigure faces, large sailing ships, and the Imperials vs. buccaneers conflict. Space Police I launched as a law-and-order counterpoint to Blacktron, while Model Team continued to grow with realistic, detail-rich vehicles for older builders. LEGO also strengthened its education arm under the LEGO Dacta name, reflecting an ongoing commitment to learning through play.
