The Avec Foundation wanted to publish a beautiful book to celebrate the twentieth anniversary of the signing of the Charter of Paris against cancer and the life-long struggle of Professor David Khayat. The tone of the layout was necessarily adapted to the subject: black and white, strong contrasts, solemnity. Our art direction had to anticipate the incorporation of photographs by Stéphane de Bourgies and calligraphy by Nicolas Ouchenir, and thus demonstrate adaptability without losing personality.
