"In fact, in a way Van Gogh is like the bad conscience of the art world because they celebrated him but not during his own lifetime when he might have benefited from the attention. And then of course there are these sunflowers, which this painting has contributed to making them iconographic. This painting is part of the reason why there is so much sunflower stuff all over the place, don't you think? People are very, very insane about these sunflowers."
