David LaChapelle Sermon from the Jesus is My Homeboy series. This art work was a way to relate to a group of people, the poor, the homeless, prostitutes, drug dealers, gangsters, and so on. Obviously the Christians group did not approve of this. But, I think this a clever way to spread Christianity to those groups of people. Maybe if they see themselves a little bit, you can convey the message of faith more effectively.
Here are some of other works of the series:
