The aim of this project was the creation of a poster and its declinations about the back cover of a book. I have chosen “Flash”, ou le grand voyage” from Charles Duchaussois. I have realized a poster, a DVD player and his booklet, and an invitation for the movie’s release.I quickly decided to design something about the Himalaya and his white snow for the poster. I decide to use pastels colors to have a smoothy atmosphere. The various waves represents all countries crossed by the junky, and the moutain and its psychedelic heart represent his last shoot. Declinations repeat this atmosphere. The DVD player takes up the design of the poster, its booklet takes up the psychedelic texture and the invitation takes up the title of the poster in a typographic declination. All designs have been created on illustrator and indesign. The result is an invitation to daydreaming.
