Нужен перевод Graffiti used to be considered wrong.We weren t allowed to do it because it damaged buildings and other public places. But now some people are so good at it that they have become known as graffiti artists. Pete Johnson is one of these artists. I began doing graffiti on walls and in streets only after I had already started working on paper.I've always enjoyed drawing and have always been good at it. Being a graffiti artist,though, is more than just drawing or painting. It' s a way of life- the way I dress, the people I hang out with, the way I see the world. Graffiti art is all of that. Like many a lot of graffiti artists, I never expected to be asked to show my work. Some artist friends and I have taken part in what is known as legal graffiti-graffiti art in public places that isn' t illegal. We've painted very large pictures on the walls of old buildings in the city-buildings that really should pull down. People often tell us how beautiful an area or building has become because of our art. They want to see more of it in their city. Some graffiti artists, like the British artist Banksy, have had huge exhibitions in car parks and on the sides of buildings.Graffiti art stops sorry i have doubts about it being a bad word. It has finaly been recongnized.
