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.
2017 LEGO Sets
2017 was a big year for the LEGO movies with the release of The LEGO Batman Movie and The LEGO Ninjago Movie. With these films LEGO gave us a number of new sets and themes around these movies, with many of them already being significant investments for collectors. We also saw a number of new themes released that year including BrickHeadz, DC Super Hero Girls, Boost and of course sets for The LEGO Batman and The LEGO Ninjago movies. However, sadly as it is LEGo did retire the much beloved BIONICLE and Mixels themes as well as the short-lived The Angry Birds Movie theme.
