Graffiti art is pictures or text painted.
It usually appears on building walls, using spray paint.
It is rarely seen in galleries and museums.
Graffiti has a long history from ancient times.
It appeared in big cities,
in the United States and Europe,
usually on subways and walls.
The common image of graffiti
is a stylistic symbol or phrase
spray-painted on a wall.
Some believe graffiti shows antisocial behaviour
trying to gain attention.
Others see it as an expressive art form.
In the 1990s a new form of graffiti appeared, “tagging”.
This is the repeated use of a single symbol
or symbols to show one’s area.
