Insights

Released in the 1960s and long retired, 1x2 Bricks is a Classic supplemental set whose Europe-only origin and short production run left sealed, high-grade copies scarce, and while condition-sensitive rarity supports collector interest, trading volume is thin and liquidity is limited.

Set Facts

The set contains 1x2 bricks in six different colors: red, white, blue, yellow, black, and trans-clear.
The set was released only in Continental Europe, excluding the UK.
Different versions of the set include combinations of red, white, blue, yellow, trans-clear, and black bricks.

About Classic Supplemental

Starting in the 1950s LEGO began individual parts sales, a practice that began with the Ferguson Tracktor in 1951. LEGO would supply dealers with wooden parts boxes and refill packs. These individual part sales would continue, at least in some markets, into the late 1950’s.

Supplemental consists of 140 sets that ran from 1960 to 1971. As of today, 890-2 Lockable Storage Box is the most valuable Supplemental set with an estimated new/factory sealed value of $439.
