Claude Monet made many paintings of "grainstacks" at different times of day in the open air in France during the year 1890. Then 79 years later along came Roy Lichtenstein, floating high on the first wave of Sixties Pop. He seized upon Monet's template and produced cartoon-dot silkscreens in a more-or-less monochrome series with flat-finish opaque pigments. I wonder if people in the far future will be interested enough to study these evidences of such a radical value-shift occurring over such a short span of time.
