1980 / Duplo

In 1980 LEGO released 11 Duplo sets across 2 subthemes. The largest Duplo set from 1980 was 2650 Farm with a piece count of 60 and a retail price of $14.75.

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.
