Commissioned creations are a growing trend. More and more you can see models that have been built for companies, friends, commemoration of events, etc. Personally I think it's a sign that, little by little, LEGO (R) is spreading beyond the worlds of toys and AFOL. Many people have seen its potential as a decorative or commemorative element. The typewriter created by Chris Maddison is a small work of art, especially when one realizes the small scale to which it is built.
