Insights

Released in the Classic era and retired, 23 Red Sloping Bricks, a supplemental Classic-era parts pack with distinctive roof-slope elements, has scarce sealed examples from its Continental Europe–only run and has attracted strong vintage collector interest, and trading volume remains thin so liquidity is limited.

Set Facts

The set contains red slopes in 2 x 2 and 2 x 4 sizes, including both standard and double variants.
It includes roof peak bricks and was only released only in Continental Europe, excluding the UK.

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 $437.
