This is a bookmark celebrating the Northern Line in London. For about four years I had to commute down the Northern line on the underground and so it has several memories for me - not many of them enjoyable because the tube is a hot, smelly and sometimes violent place. But it is always good to be reading a book and thinking that if nothing else at least I am on a bike and train now not the underground.
Bought from the London Transport Museum in Covent Garden London.
