I am unable to comment on who may or may not be Banksy, but anyone described as 'good at drawing' doesn't sound like Banksy to me.
BanksyI don't think you should have to pay to look at graffiti. You should only pay if you want to get rid of it.
BanksyI like to think I have the guts to stand up anonymously in a western democracy and call for things no-one else believes in - like peace and justice and freedom.
