As I mentioned in the description of an earlier shot, I had always thought of Piccadilly as a place rather than the street; specifically, Piccadilly Circus. The moment the lightbulb flashed on was when I saw this sign above the street.

The bonus was having an Edward Hopper-like subject in the window, though I don't ever recall Hopper using pigeons sitting above the windows as I have. But then, it's a lot easier to shoot them than it is to paint them.
