   Recommandations : « les cartes postales »
   Chaque lieu est une carte postale posée sur un bureau sombre. On choisit
   une pile (Congo, Nancy), on ouvre une carte, elle se retourne : message
   manuscrit, timbre du pays, cachet de la poste avec la ville et ses
   coordonnées, adresse tapée à la machine.
