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.
1988 LEGO Sets
In 1988, Castle introduced the Black Knights era with imposing fortresses and dragon heraldry, while Town delivered large, feature-packed sets such as racetracks and service complexes. Futuron and Blacktron—introduced the prior year—remained central to Space, with sleek exploration craft set against bold, antagonist designs.
