Supplemental sets are the parts packs of LEGO System i Leg, the System of Play that LEGO launched in 1955 to turn its bricks into one connected toy. Builders bought them to add more of the parts they needed, such as bricks in each size, windows and doors, roof bricks, plates and corner bricks. Others add details for the town plan of the time, such as Esso petrol pumps and signs, light masts, letter bricks, Danish and international flags and beams printed with Danish shop names.
1959 LEGO Sets
1959 was a year of international expansion and creative growth. LEGO established companies in France, Belgium, Britain, and Sweden, extending its European reach. The Futura department was also founded in Billund to focus on design innovation and long-term product development, including set concepts, parts, and new technologies. While few new sets were released, Futura’s work would later lead to several of LEGO’s most influential themes.
