Insights

A late-1980s Duplo release, Windmill Building Set 2404 is a vintage piece whose sealed examples have shown durable post-retirement appreciation, and its early-figure and printed windmill element add scarcity, while a smaller Duplo collector base and niche demand temper long-term conviction.

Set Facts

The set contains several blue Duplo bricks, including 2 x 2, 2 x 2 with a pin on the side, and 2 x 8 sizes.
It also features a red Duplo door/window frame with a yellow pane, a yellow 8-blade propeller rotor, and an inverted yellow 2 x 6 x 2 arch brick with a “WINDMILL” pattern in blue.
Additionally, the set includes a Duplo 2 x 2 x 2 brick figure (male, brown hair, freckles) on a red base.

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.
