DUBONNET — VIN TONIQUE AU QUINQUINA — CLAIRE MASSON — 1908 Original French advertising poster for Dubonnet, the well known quinquina aperitif. The design by Claire Masson (pseudonym Claire Mallon) depicts a young woman seated in a garden enjoying a glass of Dubonnet, accompanied by a small dog at her side. The composition reflects the elegant illustrative style of the early twentieth century, with flowing garments and a refined domestic setting typical of the Belle Epoque period. This poster is considered the only known poster design by Claire Masson, a French artist who later became a member of the Societe des Artistes Francais during the 1920s. It is also among the earliest and rarest posters produced for Dubonnet, preceding the famous advertising campaigns of the 1930s created by Cassandre for the brand.
