“The LEGO DUPLO Alphabet Truck is an excellent blend of fun and learning, offering a playful way for kids to explore letters. The large, colorful bricks are perfect for little hands, making it easy for young children to build, pull apart, and recognize letters naturally.”
 

About Duplo

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.
