An aerial picture shows the world's largest piece of illegal graffiti - stretching about 945 meters across a remote part of southern California. The graffiti, which spells out the message 'This land was out land' is set against the barren background of an active military drone testing facility, in the middle of the Mojave Desert. The artwork is 20 meters tall by 945 meters long while 250 gallons of paint were used. (Photo/SipaChina)
