A sign low down on a street corner states it is forbidden to urinate and fly-posters cover an area of wall, one of which announces that Les Halles are going. The huge central fresh food market of Les Halles de Paris was not demolished until 1971 but concerns were raised several years earlier as the fly-poster is dated March 1964. It is a French Communist Party tract calling on the workers, market traders and those who use the market to attend a public meeting with Pierre Mialet at the Salle de l'Epicerie, 12, rue du Renard on the Right Bank, Paris 4, France, March 1964.
