1) The true identity of Banksy is surrounded in mystery, but his art is instantlyrecognisable.

2)  Banksy's work has even been exhibited in art exhibitions and a lot of his works have been sold. 

3) Because of his striking images and comments on social problems, public opinion is divided. 

4) The designs are made as artistic as possible; flowerbeds are planted in skips and sunflowers down pavement grating! 

5) However, it seems that no action is usually taken by the public or the police.
