One of my neighbours is having some reforms done in his flat, and the workers covered the lift with cardboard so as not to damage it. Someone else seems to have an artistic vein, and has done these "carvings" in the cardboard. May this be a new artistic trend? Or maybe someone just was feeling childish? By the way, the "artist" has to work really fast - my block only has 5 floors, so the lift trip is rather short!
