After having walked 880 km for two months between Marseille and Paris to collect thousands of masks thrown by the roadside, Englishman Edmund Platt and Frenchman Frédéric Munsch arrived in the French capital on Saturday. To help raise awareness of the problem further, the Franco-British duo teamed up with a street artist from Nice who exhibits masks under glass, displayed under street signs in Paris. And they are offering an "aperitif garbage collection" on Friday evening in front of City Hall (Hotel de Ville, Eds.).
