“[W]hen I did paintings based on Monet’s I realized everyone would think that Monet was someone I could never do because his work has no outlines and it’s so Impressionistic. It’s laden with incredible nuance and a sense of the different times of day and it’s just completely different from my art. So, I don’t know, I smiled at the idea of making a mechanical Monet.”
Roy Lichtenstein quoted in Michael Kimmelman, Portraits: Talking with Artists at the Met, The Modern, The Louvre and Elsewhere, New York 1988, p. 93
