About LEGO Duplo Supplementary

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.
1984 LEGO Sets
1984 marked the launch of the LEGO Space "Futuron" subtheme, which introduced a more futuristic and modern design aesthetic to the broader Space theme, captivating fans with new minifigures, vehicles, and space bases. Additionally, 1984 saw the birth of the LEGO Castle "Crusaders" and "Black Falcons" factions, enriching the Castle theme with more intricate storylines and detailed sets.
