I haven't got a picture of it ATM, but there is someone (I'm guessing they live in or around toton) who graffiti's the top half of a cats head in purple onto the side of EWS wagons, I've seen it a few times.
There was also a sign (the blue one with the the white person on one side with a line and a bike on the other) on an underpass beneath a roundabout near th McDonalds in canary wharf, with a copy of it graffitied onto the wall, with 'hidden shadow' written above it. I never got chance o photograph it before it went
