Flemming Andersen was born on June 2, 1968 in Copenhagen. In his childhood, he enjoyed Scandinavian comics, such as works by the Danish cartoonist Storm P., and Franco-Belgian comics. As a student, it was clear for Andersen to become a professional artist. After finishing school and military service, he searched for a job as an illustrator, preferably at advertising agencies and newspapers. Andersen learned that the media group Egmont, the Danish publisher for Disney comics, searched for artists.
