Summer by Auguste Renoir, 1868
What is a summer vacation other than spending it with your kids, your wife and your, erm, young mistress? Turns out Renoir received negative attention from the Salon when he decided to depict the (barely pubescent) girl as a nude Diana. Go figure. Nonetheless, I find the ribbon in her hair a great detail to her free spirited, and perhaps a bit risqué, ensemble.
