Wandering aimlessly through Covent Garden, I walked inside the doors of the London Transport museum and found myself in its gift store. There, I found an enormous collection of vintage Underground posters - colourful, vibrant, dazzling. Having taken the tube from a young age and, now living abroad, buying a couple of prints like a fine idea. After all, there’s nothing like the Underground to make a Londoner feel warm and fuzzy!
