What attracted me about my mirrors was the idea of having nothing manipulated in them. A piece of bought mirror. Just hung there, without any addition, to operate immediately and directly. Even at the risk of being boring. Mere demonstration. The mirrors, and even more the Panes of Glass, were also certainly directed against Duchamp, against his Large Glass.
