Trees and Signs (1969 version with old style trees and 3 bricks)

The 990-2 Trees and Signs set was introduced in 1969 as a supplementary accessory pack for the burgeoning LEGO System. Designed to enhance the playability of the era's town and road layouts, this set provided builders with essential environmental elements, specifically the distinct, older-style conical trees and a small selection of basic bricks. These accessory sets were a cornerstone of the company's early strategy to provide modular, versatile components that allowed children to customize their growing cityscapes beyond the standard building kits.

The design of the 990-2 reflects the aesthetic sensibilities of the late 1960s, characterized by a focus on structural simplicity and open-ended creative play. While these sets were rarely credited to individual designers in the way modern sets are, they were the product of a collaborative design team in Billund focused on expanding the versatility of the brick. The set was well-received by consumers of the time as an affordable way to add realistic detail to displays, serving as a functional staple in the collections of hobbyists during this foundational period of the brand.
