The organisation Arts et Lettres de France donated this poster and bottle of champagne to the museum with the statement: 'These objects represent the Bastille Day Ball held in London every year, which emphasises how welcome the French community feels in London and shows its desire to share with British friends the pleasures of joyful celebration.' Bastille Day is a national holiday celebrated in France on 14 July. It marks the storming of the Bastille prison in Paris, one of the events of the French Revolution of 1789.
