Famous quotes containing the word signs:
“Among all the modernized aspects of the most luxurious of industries, the model, a vestige of voluptuous barbarianism, is like some plunder-laden prey. She is the object of unbridled regard, a living bait, the passive realization of an ideal.... No other female occupation contains such potent impulses to moral disintegration as this one, applying as it does the outward signs of riches to a poor and beautiful girl.”
—Colette [Sidonie Gabrielle Colette] (1873–1954)
