'Les Griffes du Marais'.
After his artistic studies, Patrick Amblevert began to work for several studios specialized in wine labels. He also pursued a career as an advertising artist. From 1989 to 1994, he drew two albums in the series 'Les Griffes du Marais' with scripts by Eric Corbeyran at Vents d'Ouest. The series was transferred to Édition Hélyode in 1995, and for this occasion, Amblevert used the pseudonym Blue Green. Amblevert also took over the series 'Foc' from Yves Bordes for one episode at Soleil Productions (text by René Durand).
