About LEGO Duplo Building Sets

The LEGO DUPLO theme 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.
1975 LEGO Sets
In 1975, LEGO continued to release a wide range of new sets and themes, including the LEGO Land Busters theme, which featured models of construction vehicles such as bulldozers and excavators. 1975 was also the year that LEGO introduced the LEGO Basic Building Set, which included a selection of basic bricks in various colors and shapes, as well as instruction booklets with ideas for building projects. Other notable sets and themes released by LEGO in 1975 included the LEGO Space theme, which introduced new spaceship models and minifigures, and the LEGO Castle theme, which expanded upon the castle sets released in previous years.
