Les Fleurs du Mal Possibly 1966

"Les Fleurs du Mal" is a book cover designed by Georges Rouault, a French artist known for his expressive and often dark style. The cover features a simple, textured design with a blue-green background and a vertical blue stripe on the left. This design is reminiscent of Rouault's later works, which focused on simplicity and raw emotion. While the cover might not be as elaborate as his paintings, it still captures his artistic sensibility.
