One of my new favorite websites is hosted by The New Yorker's art director, Françoise Mouly, and her daughter, Nadja Spiegelman. Called "Blown Covers," it's a monthly online contest in which gifted artists submit illustrations on a chosen topic and Mouly showcases the best, along with critiques and commentary. Fascinating. (Mouly is also the editor of 2012's anthology of Best American Comics.)
Below are some of my favorites on the theme of the book.
