Made for a short-dated use in public space posters are ephemeral products par excellence. The mass media promotes new commercial articles which are no more innovative the next day or invites us to cultural events which shortly belong to the past. Therefore, sustainability seems to be incompatible with poster design. Nevertheless, some graphic designers reflect within their work a more ecologically worthwhile application of posters. Exemplary, the exhibition « Déjà Vu – Recycling strategies in Poster Design » presents four different approaches of Swiss graphic designers for re- and upcycling ideas in cultural posters, while representing an institution or an event with a recognizable identity.
