Graffiti isn't something we especially want to encourage; but if there was ever encouraging graffiti to remind us some people just want to make stuff that looks nice, this was it. A short lived set that popped up at the train station not terribly long ago.
When I went to England, I was expecting to be able to find Banksy here, there and everywhere. Despite being in London, one of the favourite Bansky spotting locations, this simply isn't the case, as most of Banksy's work is confined to dark alleys, tunnels, corners and other places that your everyday London tourist is unlikley to wander down. Additionally, anything that IS big and public gets taken away so quickly that you'd never see it.
