Leave it to Dr. Seuss and Maurice Sendak to create ads that were every bit as charming as their books. You can find the Dr. Seuss Narragansett Beer poster at Abebooks.com, as well as one he did for war bonds featuring the aptly named Squander Bug. There’s also one by Maurice Sendak that promotes Freedom to Read that has me singing “Chicken noodle soup with rice.” Don’t have $1500 lying around to spend on a poster by a favorite author? M+E has a new line of posters featuring homes of famous authors, including Poe, Emily Dickinson and Flannery O’Connor. — Sarah L.
