Graffiti 

Graffiti art is an art form. The reasons, including aesthetic criteria, as to why it is an art form far outweigh the criticism of illegality, incoherence, vandalism, a fear crime and nonstandard presentation. On  the other hand graffiti is art , a culture and it's historical and meaningful. Graffiti was born in US.

Graffiti is also criticized for being too hard to understand, but certainly this cannot keep graffiti art from being art anymore than the obscurity of abstract art or Picasso's cubism prevents either one of those hard to understand art forms from being considered as art. Goldman's aesthetic theory is of use to clarify the problem of location and presentation in relation to graffiti art.

Therefore, graffiti in the form of spraycan art is art. It has form, color, and other base properties as well as an arrangement of these elements into structures that qualify it aesthetically as being art. Just doing something with spraypaint might make it graffiti, but it does not necessarily qualify it as art or graffiti art. In addition, when the spraycan art is analyzed according to the artist's intention and value to audience, there is even more evidence to suggest that it is genuine art. The only obstacle that has hindered the general acceptance of graffiti art is its location and presentation. However, the instances of acceptance of graffiti art by the art world shows that conventional methods of presentation are not all that matters in determining if something is art. And graffiti art is not to be disqualified as art simply because it might appear unsolicited. In short, graffiti in the form of spray can art is art like any other work that might be found in a gallery or a museum.
