About LEGO Block Box
LEGO Block Box (set #071) is a small, compact build with 24 pieces from the Duplo theme, released in 1979. The Duplo line features larger bricks designed for toddlers and preschoolers aged 1-5. Designed for young children aged 1+, the larger Duplo bricks are easy to handle and safe for small hands. This set dates from 1978, the landmark year LEGO introduced the minifigure along with the first Castle and Space themes.
Set Highlights
- Oversized Duplo bricks — safe for children aged 1+, no small-parts risk.
- Compatible with all standard LEGO sets — bricks extend naturally into other sets you own.
- Play-focused build with interactive elements designed for 1+ builders.
- Vintage 1979 release — increasingly rare in complete, unplayed condition.

Parent & Child Building Activity
Duplo bricks are sized for small hands. Building together is the intended experience — simple steps and large pieces make it accessible for children aged 1+.
