The Metropolitan Museum of Art has put hundreds of high-resolution, copyright- free images from its collections online! Oh what a tzimmes I'm in! Looking at stuff like this is such a drug for me. I've barely recovered from the hours I've spent viewing and downloading beauties from the Getty collection (which I promise to share with you ere long).
Meanwhile, here is a sample image from the Met appropriate to the season: "Summer" (1935) by Balthus (Balthasar Klossowski). As with many of the images newly available, the painting is not currently on display in the museum. One can really examine artworks in detail this way—what a boon for researchers and art lovers!
art books from the Met on hand.
