Now that I like - consider yourself saluted ;)
Nowhere near as good - but in my PhD years there were 5 of us in a house in bounds green - much sign stealage - including the following: on the toilet door "haringay council - no dumping £2000 fine" on the wall inside the bog "haringay council - no ball games" and on the wall in the upstairs bog "Thames water - no swimming" ... we were easy to amuse back then...

On my bedroom door
I have a sign stolen from the post room of a certain Govt Department saying "Bomb Area. Do Not Enter"

Some friends at university lived in a house where there were 4 or 5 blokes an done girl. They went to France once and while there they stole a direction sign for a town. They took it home and put it on the wall of the hallway pointing towards the girl's room. The town?
