Graffiti is a form of self-expression through inscriptions or pictures on walls and other surfaces. It has existed since ancient times but the first known graffiti writer was Taki183 in New York City in the 1970s who would tag his name throughout the city. Graffiti ranges from simple tagging to complex murals and styles, with skilled writers able to tag their name in only a few seconds. While drawing graffiti without permission is considered vandalism, some professional writers earn money painting for clubs and shops.
