Leon Keer is the master of optical illusion. The 'Dutch JR' plays with perspectives and creates a whole new world. One in which Snow White is stuck under a door. Or a world in which you unexpectedly enter a seventies living room. This is his first monograph. He allows the reader an exclusive look into his world and imagination. How does he work? And how does a wild idea develop into a gigantic 3D artwork? AUTHOR: Leon Keer is one of the world's most important 3D Street Art artists. His works are to be found all over the world: in Europe, the USA, Asia, Russia, Mexico, the United Arab Emirates, Australia and New Zealand.
