Only few days ago, we have featured some of the most interesting chalk drawings by Edgar Müller. But this hasn’t stopped Edgar from doing some more excellent work, more precisely in Moscow, Russia. Pictured below, you may find a colossal 3D Chalk Drawing, just like Edgar usually does ‘em. If you continue scrolling inside this article, there are few more shot of how the picture came to be. Check out the concrete plaza in Moscow, before work on “Duality” has even started, as well as the finished product. More images after the jump.
