Bør Børson jr. is a satirical novel from the boom period during World War I, written by Norwegian writer Johan Falkberget. It was first published as a feuilleton in the satirical magazine Hvepsen in 1917, then again printed as a feuilleton in the newspaper Nidaros, and issued as a book in 1920. The story was a great success, and has later been adapted into two films (one in 1938 and one in 1974), a comedy, a musical, and a comic series. Source: Wikipedia (en)
