Le baiser de Opéra. Paris 1950 by Robert Doisneau

Robert Doisneau is best known for his street photography, his most famous example being 'Kiss in front of the Palace of City Hall' (1950). But he took thousands of photographs striving to capture the pulse of Parisian life. Like his contemporary Brassaï, Doisneau liked nothing better than to walk the streets never knowing what sights he was to encounter.
