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.
2007 LEGO Sets
For collectors, 2007 proved to be an important milestone for with the release of the Modular Buildings theme which initially included Café Corner (10182-1) and Market Street (10190-1). Also, the Star Wars license with LucasFilms was originally planned to end that year, but is renewed. To celebrate Star Wars' 30th anniversary, LEGO released a free, 14-carat gold C-3PO minifigure. 2007 also saw the discontinuation of a number of themes including Aqua Raiders and Knights' Kingdom II but also so the introduction of the Thomas and Friends theme.
