"Another aspect of the 'readymade' is its lack of uniqueness.. ..the replica of a 'readymade' delivering the same message; in fact nearly every one of the 'ready-made's existing today is not an original in the conventional sense. Since the tubes of paint used by the artist are manufactured and ready made products we must conclude that all the paintings in the world are 'ready-made's aided' and also works of assemblage."
