“Graffiti on canvas? So now they’re painting graffiti on canvas, Graffiti can’t be on canvas. Graffiti exists on walls and trains” What LEE says corresponding to “Wild Style” becomes abolished during the plot when he paints canvas himself. He is taken with two things. In the first place it’s the challenge to capture the lightened skyline of the new york on canvas and secondely the money paid for his painting.
That are two big points, which distinguish painting on canvas from painting on walls and train in the city.
The canvas has a natural surface which first of all exists by its own not belonging to a certain environment, it does not depend on the urban structure, Size and distinction are making it possible to work more precisely than on a train or a wall. But there are also writers who are using their “street knowledge” straight on the canvas. As an easy to handle and portable piece, the canvas gains more and more sympathy.
A canvas is tradeable, collectable or eather conserved in a museum.
One of the first impression of new york subway graffiti in Germany was made possible through various exhibitions in art galleries, showing the works of LEE, DONDI, FUTURA 2000, SEEN, CRASH, DAZE, A ONE, RAMMELLEZEE, LADY PINK etc
So graffiti on canvas is the next step of writing into another area. Some of the “bombers” may dislike the idea of selling out the own art, but if one is occupied twenty-four hours a day dealing with his art, it’s more than ok to make some cash money. That allows the artist work not to be “good” but tradeable.
Which is exactly what DONDI means when he talks about  the “Battle above ground”.
