Illustrator J. Oval was a Brit named Ben Ostrick who painted under both his pseudonym and real name. His crisp illustrations helped make Pan Books, which debuted in 1944, one of the most eye-catching mid-century imprints. Pan is still around as part of Britain-based Macmillan Publishers, which is in turn owned by the Georg von Holtzbrinck Publishing Group of Germany. Many of Oval’s pieces for Pan were paired with works so obscure they’re almost impossible to find today, but above you see a good-sized collection, including a few we managed to turn up that haven’t been widely seen. With few exceptions they all use the same formula, though he would occasionally deviate by painting a fully rendered background, or populating a scene with more than one or two figures. You can see a couple more Oval covers in our collection of Asia-influenced paperback art here, and we also shared a small collection of his work back in 2011 that you can find here.
