LEGO System in Play 700/5

Godtfred Kirk Christiansen of LEGO (believed to be a contraction of the Danish expression leg got, which means “play well”) created his own version of toy plastic bricks in 1949, first called Automatic Binding Bricks. LEGO’s patented stud-and-tube interlocking system made it easy for blocks to stick together and enabled the construction of large, fanciful structures.
