Public Art of Athens

Athens is full of graffiti and other street art; and some of this is probably commissioned by the shops or advertisers. Unlike Lesvos, I didn't see a lot of political protest art; which I found quite strange. The majority of the good art is around the Psyrri suburb; which also had a small Asian community (Bangladeshis and Chinese mainly it seems); but the art didn't seem to have any specific ethnic origin.
