Carnaby Street 1960's - "How constantly and overwhelmingly the advertisements, radios, newspapers and movies play on us! But in thinking of them remember that to them they are tokens of mockery. These bright colors may fill our hearts with elation, but to many they are daily taunts. Imagine a man walking amid such a scene, a part of it, and yet knowing that it is not for him." - Max, 'Native Son'
