This last photo is particularly cool because the eyes make up the rest of the faces when the train passes through.
this artist really inspires me on so many levels. i think he is doing what people only dream to do. he puts large scale portraits of people onto buildings in communities all over the world. his choice of subjects is quite simple: people that he finds in urban ghettos.
in his bio on his webpage, he describes himself as "an undercover photographer [who] transforms his pictures into posters and makes open space photo galleries of our streets."
here are some examples of his work!
