20 street art works on the verge of art and hooliganism

According to one version, street art appeared during the Second World War, when a Kilroy worker began to write "Kilroy was here" on every bomb crate. Since then, street painting has spread all over the world, and there is probably no city where it would not leave its mark. Street art is still considered illegal in many countries. 

But in some cities, the authorities meet street artists halfway and hold special festivals and even protect street art objects, such as Banksy's works. In a word, street painting, like any art, is to someone's liking, but someone considers it just hooliganism.
