Polarizing American artist Andrew Wyeth, who painted "Christina's World"—my favorite painting ever, go see it in the flesh canvas at the Museum of Modern Art—died yesterday at age 91.

The New York Times has a full, and worth-reading, obit here. He was an interesting figure—a popular and successful rural realist, disdained by many of the New York artsy elite. Plus "Christina's World"—which depicts a paraplegic woman, who Wyeth used as a subject many times, outside of her home in Maine—was given homage on The Simpsons, as you can see below.
