A poster functions like a mirror. If its author hasn't managed to project his own vision, the visitor cannot plunge their own into it. If, under the pretext of providing a response to an imposed subject, these two visions do not sparkle with their independence of mind then the image would be meaningless.
—Étienne Hervy, M/M Paris
The language barrier is when two people speak the same language. It is no longer possible for them to understand one another.
—Adieu Gary Cooper, Romain Gary, Gallimard, Paris, 1969
