Louis Salvérius, who mostly signed his work Salvé, is known as the initial artist to draw the successful series 'Les Tuniques Bleues' ("The Blue Jackets", 1968) in Spirou. He designed the two protagonists, Blutch and Chesterfield and, despite drawing in a more humoristic style, still managed to captivate readers with his striking artwork. Unfortunately Salvérius died unexpectedly at an early age. His successor, Willy Lambil, reshaped the comic's graphic style and drew all next albums. As a result, the general audience is arguably more familiar with Lambil's version than Salvérius' one. Nevertheless, Salvérius and writer Raoul Cauvin built the foundations on which the popular series is grounded and which helped it become such a beloved best-seller from the start.
