As a hint, you can try looking for the title "Typographic Cities" and search the streets for something interesting.

As a further note, I'd like to say that the intended place for this would be a tube or a train, as many of my journeys to and fro university consist of me standing squashed like cattle in a tube packed full of people, and with nothing to do but trying to avoid looking at someone intentionally. Engrossed in this poster would be an interesting way to spend that journey.
