Raoul Auger is mainly known for his illustration work, but his exploits in the comics field are quite interesting. For Tintin, he created several stories in direct colors in the 1950's. This technique was hardly used by comic artists at the time. Auger's first comics appeared in 1947 at Siècle publishers. There, he produced several episodes of the 'Tom-X' series under the pseudonym Ariel. A year later, he illustrated 'Le Mystèrre du Sous-Marin' in the collection Bob et Bobette of Dargaud publishers.
In September 1949 Auger joined Tintin, where he started out doing several covers and illustrations. He continued his work with some novel adaptations ('Le Grand Cirque') and historical biographies ('L'Étonnante Aventure de Roald Amundsen'). He was also active for Fleurus publishers with several comics in the collection Belles Histoires et Belles Vies. Raoul Auger drew occasional comics until 1970 for such magazines as Âmes Vaillantes ('Le Trésor Maya', 1954-1955) and Pilote (the educational pages 'L'Armée Française' and 'Calypso' in 1960-61) and Lisette ('Michel Strogoff', 1970).
