Graffiti: art or crime?

Graffiti, have you ever seen one? They're everywhere, I'm sure that you often see them. Graffities appeared last century, about 60's in New York. At the begining they were only tags of people with their nicknames
and usually with the number of their streets like Taki 183 and Kilroy.

Some years later, other types of that urban art emerged, those had more colours and less letters. They were painted in underground stations, then with  Hip-Hop motifs, and nowadays they're also used to decorate places (private graffiti), others called slogans that espress a personal opinion etc...

In any case, graffiti is an art that usually needs a very big wall to be done and that fact prevents that some artists can practice it. Therefore, they are forced to paint in private properties and commit a crime. There are some places destinated for that but no many yet.

Next time I'll talk about a unusual artist call Juan Francisco Casas. See you and remember... Don't be afraid of art ;)
