If you are a fan of Louise Fitzhugh and Kay Thompson —and you have an extra hundred bucks lying around— you can find rare copies of this 1961 book, The Wonderful Adventures of Suzuki Beane by Sandra Scoppettone. A beatnik take on Eloise, it tells the story of a naughty little hipster who lives on Bleecker Street with Hugh, her Beat poet father, and Marcia, her spaced-out sculptor mother. The distinctively grotesque and scratchy looking illustrations (by Louise Fitzhugh) look straight out of Harriet the Spy.
I was hoping I could find a copy of it through the library, but no luck. Fortunately, you can read the whole thing here on Scribd.
Also, there’s this amazing 1962 pilot for a TV show (never made) based on Suzuki Beane. Totally worth watching:
