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.
1990 LEGO Sets
1990 was a creative high point, expanding LEGO’s thematic depth. Pirates, launched in 1989, continued to thrive with new ships and island adventures, pioneering expressive minifigure faces. The new Model Team line targeted older builders with detailed, functional vehicles emphasizing realism. LEGO Space introduced M:Tron, a red-and-black rescue faction featuring magnetic crane elements and transport vehicles, establishing a new civilian layer within the Space universe.
