Appie Kim en het Spookkasteel (1950)
During World War II, Joop Du Buy participated in a contest by a company that was looking for comic artists, with the famous artist Kannegieter on the jury. He was accepted and put to work on the anti-semitic animation film 'Van den vos Reynaerde' by the Nenasu (the national socialist publisher). When the film was completed and the studios closed down, Du Buy applied for a job at the Toonder Studios, but was rejected. He was then sent to Germany to work at a weapon factory.
Upon his return in Holland after the War, he went to work for communist newspaper De Waarheid, that published his comic strip 'Appie Kim' from 1949 to 1951. He also made 'De Avonturen van Bollie, 't Ondeugende Olifantje', with writer Karel ten Hoope. He eventually returned to Germany where he started a chain of fashion shops. Back in Holland in 1974, he remarried and drew the erotic underground comic 'Nimfke en de Nonnenneuker'.
