The LEGO DUPLO theme was introduced as far back as 1969 and is designed for children ages 1 to 5. It features DUPLO figures which are much larger than minifigures and DUPLO blocks which are about twice the length, width, and height of a standard System brick. Like LEGO System, DUPLO also has subthemes that are often junior versions of System themes, like Pirates and Castle and licensed themes like Disney and Super Heros.
1970 LEGO Sets
1970 marked a period of transition and consolidation for LEGO. The company began reclaiming U.S. market rights from Samsonite following founder Jesse Shwayder’s death, leading to full control by 1973. In Italy, LEGO responded to import restrictions by launching Minitalia, a localized line produced from 1970 to 1975. The long-running Town Plan theme was discontinued as LEGO moved toward standardized scale and unified play systems. While largely a structural year, these shifts laid the groundwork for the innovations of the mid-1970s.
