Tim Burton’s Big Eyes only just released a trailer for its December release, but already it’s created a resurgence of interest in Margaret Keane, the ’60s and ’70s artist played by Amy Adams in the film. Framed prints, lithographs, and small paintings of Keane’s signature doe-eyed children are now going for as much $8,500 a piece on eBay, spurred in part by excitement around the movie. Burton himself reportedly has an extensive collection of Keane’s art already—and he’s just one of many Hollywood admirers. As The Hollywood Reporter notes, Keane has painted portraits of Joan Crawford (who used it for the cover of her autobiography), Kim Novak, Jerry Lewis, Natalie Wood, Robert Wagner, and Burton’s ladies Lisa Marie and Helena Bonham Carter. If any of them wanted to sell theirs, now would be the time.
