1955 / System i Leg / 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.

1955 LEGO Sets

1955 was a very important year for LEGO. In this year, Godtfred Kirk Christiansen attended both the attended the London and Nuremberg Toy Fairs where he eventually came up with the LEGO System of Play and the now classic Principles of Play. These principles were issued to every LEGO employee in 1962 and still stand as the core principles of the company. Godtfred organized the existing LEGO Mursten sets and modeled new designs around a single, common theme - a townscape or street scene. After nearly a year of development the result was the LEGO Mursten System i Leg (System of Play). The System i Leg (System of Play) was unveiled at the Nürnburg Toy Fair in February 1955 but the reaction was less than positive.
