the words of the prophets are written on the subway walls

theres a type of graffiti that i like to call "public service graffiti". its the type of graffiti that says something clever, or is a really beautiful picture or design. i think that the world would be so much of a better place if everything was covered with art. if people were all trained in the skills of expression through imagery, and if every surface possible was covered with messages conveyed through their images. if the whole world was an art gallery. i think that that is what the real purpose of graffiti should be.
here are some amazing paintings by street artist banksy, of whom i am a huge fan.
