Another massive mural by the Catalonian artist Aryz is in the books. Freshly painted for the CityLeaks urban art festival in Cologne, Germany, the festival itself aims "to demonstrate that art will not endure censorship, but can respond loudly and critically to its environment," which Aryz has definitely achieved. His signature muted and stark skeletal piece confronts the public space with notions of death, while still keeping a witty humor through the additions of a top hat and bow tie.
