After I read The Hare with the Amber Eyes, I went to the Art Institute to see a Renoir that one of the book’s (real-life) characters had owned. And I somewhat blame my penchant for living on a dime in small, urban apartments by how taken I was, as a 14-year-old living in Indiana, by that enchanting 90-second opening of An American in Paris. So I put the question out to my Millions colleagues: What works of art have you been introduced to by other works of art?
