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.
1970 LEGO Sets
By 1970, LEGO grew to over 1,000 employees. The LEGO Group started the process to regain the LEGO license from Samsonite in the United States market after the founder of Samsonite, Jesse Shwayder, died. By 1973 LEGO will take control of all US LEGO sales. As LEGO continues its European growth, in Italy, the Italian Parliament restricts the import of LEGO products and LEGO responds by creating their own Italian manufacturing subsidiary called LEGO Minitalia. In 1970 LEGO produced their first sets on the Minitalia theme which were essentially Basic systems. In total from 1970 until 1975 there were 21 Minitalia sets produced. During the same year, the long-running Town Plan theme was discontinued as this was part of the phasing out of multiple scaled models.
