An advert to die for

Sometimes we see something that just makes us stop and say OMG! This is an advert that has been carefully posted on the wall by the track at an underground station is just one of those occasions.

We have no idea where this is, but it looks like it says Berlin, but we could be wrong, wherever it is this is a cool advert and whoever thought it up, is very smart indeed!
