Loupot, another pioneer of the French modern poster, had his own special, personal style, characterized by simplicity and synthesis of ideas. He worked for 5 years in Switzerland as a typographer and was very successful with his posters. In 1923 he was called back to Paris by a French printer. In 1930 he, Cassandre and Maurice Moyrand founded their own studio, Alliance Graphique. The apéritif St Raphael became his most important client (1936) and this co-operation lasted far into the 1960s. In 1945, Loupot designed the famous St Raphaël waiters and used them as a logo on transport, advertisements and posters. He also turned them into murals; three thousand of these were handpainted onto the sides of houses across the whole of France. Other clients included Peugeot, Nicolas, Twinings and Sato cigarettes, for whom he used elegant female figures. His DOP poster, an outcome of a new technique, appeared in the streets of Paris like ‘a smile in the everyday grey’, according to Henrion.
