The LEGO System i Leg Mosaic theme, introduced in the mid-1950s, focused on creating artistic designs using small, colorful tiles. This theme includes sets such as the "1300 LEGO Mosaik Set Small" and the "1301 LEGO Mosaik Set Large." These sets allowed builders to create detailed mosaics by arranging 1x1 tiles on a baseplate, encouraging creativity and fine motor skills. The 1300 set provided a smaller selection of tiles and simpler designs, while the 1301 set offered a larger variety of tiles for more complex and detailed mosaics. This theme showcased LEGO's versatility beyond traditional building, promoting artistic expression and design.
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.
