LEGO Supplementaries were sets released during the early days of the LEGO system. These sets were designed to supplement and expand upon the building possibilities of existing LEGO sets. Instead of being complete stand-alone models or kits, Supplementaries provided additional bricks, special parts, wheels, windows, doors, gears, or even motors. These sets were especially useful during an era when LEGO's product line was simpler and less specialized than it is today.
1985 LEGO Sets
1985 expanded everyday play in Town—airports, transit, and rescue—alongside incremental growth in Castle and Space. Technic emphasized functional builds with working steering, suspensions, and gear trains, continuing to position the theme as LEGO’s bridge to real-world mechanics.
