LEGO Town Plan was a theme introduced in 1958 and lasted until 1966 and was under the System i Leg (System of Play) theme. The theme was unveiled at the Nuremberg Toy Fair in February 1955. LEGO Town Plan originally consisted of the existing 700 series LEGO Mursten sets, several new HO 1:87 scale accessories, and a vinyl play mat. However, over the next several years the system was expanded with both new building sets.
1956 LEGO Sets
1956 was another important milestone year for the LEGO Group. In this year LEGO began its expansion into various neighboring European markets including Germany and LEGO opened its first foreign sales company in Hohenwestedt, Germany. As LEGO began to expand sales they also simplified the Mursten theme. Since 1954 LEGO had sold both the old panel-like windows and doors and the new window system that relied on the studs for attachment. In 1956 the old windows were dropped. The slotted bricks were now obsolete and were replaced with a new solid wall design, the first change to the brick since 1949. This new, simplified system would be the only toy offered in new foreign markets.
