Letters become graffiti - graffiti becomes type.
Every writer has his own handwriting, his own inimitable style influenced by his cultural, social and personal background.
Nowadays, more and more galleries care about graffiti.
However, they prefer to show what they call "street art", meaning fancy puppets and other kinds of illustrations rather than the origins of graffiti writing.
But what about those brilliant contemporary artists who create thousands of different types each day?
Most galleries don't care about them, so street-alphabet is trying to make a change.
