R.I.P., Andrew Wyeth.
He was one of the artists we studied a lot when I was in high school, and I remember going to the "Helga exhibit" at the Brandywine River Museum, when I was a senior, I think. The hallway in the wing housing the art classroom had a print of Christina's World.
I love the color and detail in his work, and the subjects (nature, people) feel very familiar and accessible.
If you don't know much about his work, I encourage you to look some up. You just might enjoy it.
