This work is Joan Sfar’s collection of all his material for his movie about Gainsbourg, gathered together in a beautiful story. This is not only an extraordinary volume containing more than 150 pages of comics, illustrations, storyboards, research, but a historical book, to be looked at as much as to be read, about the great genius of the French song. An art object that is bound to become one of the pillars of in Sfar’s career.
