Field Trip: Banksy

-My knowledge of street art is fairly limited, so whenever I pass a mildly subversive piece of art pasted onto a wall in New York or Los Angeles I am inclined to wonder if it was done by Banksy, the English graffiti artist who manages to be the face of the street art movement despite never actually showing his face. However, my first confirmed sighting took place on my recent trip to LA, when I happened upon these pieces on Beverly Boulevard and Melrose, respectively. These were cool to see, but unfortunately not as cool as the Guantanamo detainee Banksy put inside Disneyland's Thunder Mountain Railroad on his last trip to California.
