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.
2012 LEGO Sets
2012 was a landmark year highlighted by LEGO’s 80th anniversary and major licensed expansions. LEGO The Lord of the Rings and The Hobbit joined the lineup alongside Marvel and DC Super Heroes, establishing enduring partnerships with both comic universes. LEGO Friends debuted, introducing mini-doll figures and Heartlake City, becoming one of LEGO’s most successful modern themes. Other launches included Monster Fighters, Disney Princess, and Dino. Alien Conquest, Atlantis, Pharaoh’s Quest, Kingdoms, and Harry Potter retired, though Harry Potter would later return in 2018.
