From Christopher Chabris' review of Duncan Watts' "Everything is Obvious," emphasis mine.

Common sense is also inclined to conclude that individual successes (and failures) are determined by inherent qualities rather than by unpredictable circumstance. Mr. Watts asks why the "Mona Lisa" is the most admired painting in the world today—why most people believe it to possess unique, timeless features that set it apart.

Before the 20th century, the "Mona Lisa" wasn't even the most popular painting in the Louvre. But in 1911 it was stolen, smuggled to Italy and exhibited widely before being returned to France, whereupon Marcel Duchamp defaced a reproduction of it and labeled his work with an obscene pun. The painting rocketed to fame, its pigments and brushstrokes unchanged. The "Mona Lisa" is the artistic equivalent of the investor who did nothing special until he got lucky a few years (or quarters) in a row and was fêted as a genius.
