Say NO! (by The No Foundation)
This is hardly funny if you don't travel on the Underground. But if you do, The No Foundation will make you laugh with their self made no-stickers. A pity I still haven't found any of those in the tubes I've travelled in, but I'll pay more attention from now on…
Which also reminds me that I noticed recently that the Victoria line carriages do have that kind of stickers in the space reserved for advertisement on the walls "by default", although usually they are hidden with the advertisement itself. So if there's no advertisement, there's always some kind of ban: keep your music down, don't put feet on the seats… etc

mmm, at http://www.thenofoundation.com you can read "no signs (2004-2005)" as the name of the project.
Perhaps they've stopped to put stickers and the old ones have been removed from the tube, so it will be hard to find them.
Just a guess :)

Once again thanks for the link :-)
It is quite hard to spot these stickers as I'm sure London Underground take them down as soon as they see them up. But keep looking they are very funny!
