Fleurs sauvages

Since 1987, the anthropologist Pierre-Jacques Dusseau, who works in prisons, has collected objects made by detainees. Refused by museums of ethnography, these everyday objects and artistic creations are gathering dust in his attic. Each one has a story that sheds a different light on penal institutions – and these stories, no one tells them better than Pierre-Jacques.
