About LEGO Flags, Trees and Road Signs

LEGO Flags, Trees and Road Signs (set #939) is a small, compact build with 20 pieces from the Universal Building Set theme, released in 1972. The Universal Building Set line features classic brick assortments for general building. This is a starter-level build suitable for ages 4+, with an estimated build time of 10-20 minutes. This set dates from the pre-minifigure era, before LEGO introduced its iconic yellow-faced figures in 1978.

Set Highlights

  • 20 pieces at starter complexity — a 10-20 minutes build.
  • Compatible with all standard LEGO sets — bricks extend naturally into other sets you own.
  • Play-focused build with interactive elements designed for 4+ builders.
  • Vintage 1972 release — increasingly rare in complete, unplayed condition.

Who Is This Set For?

Gift for Ages 4+

The starter difficulty makes this accessible without being trivial — a well-matched gift for LEGO fans in the 4+ age range.

Weekend Build Project

20 pieces with an estimated 10-20 minutes fits comfortably into a focused afternoon or weekend session.

Expanding a Universal Building Set Collection

A solid addition for collectors building out their Universal Building Set shelf. Introduces parts and builds that complement other sets from the same line.

Build Tips

1

Check the piece count on the bag against the parts list before starting — knowing what you have prevents mid-build surprises.

2

Even in small sets, connection order matters. Follow the steps rather than building sections independently.

3

Vintage sets may show slight color variation from modern LEGO due to different ABS formulas. This is normal and part of the set's character, not a defect.

Finding Instructions

Instructions for older sets like #939 (1972) may not always be available on LEGO.com. Try searching the set number directly, or upload a photo of the bricks to LegoFinder — the AI can identify vintage sets from their parts.
