Gruau became one of the best known and favorite artists of the haute couture world during the 1940s and 50s working with Femina, Marie Claire, L'Officiel, L'Album Du Figaro and an assortment of "high-style" magazines.
[3] Born Renato Zavagli Ricciardelli delle Caminate in Rimini, Italy, on 4 February 1909, Gruau was the son of an Italian count but instead of following in his father's footsteps and accepting the job of royal military commander, his passion and inclination for arts led him to a love and pursuance of fine arts.
At fourteen, Gruau began to support his mother and himself by selling drawings to the Milanese fashion journal Lidel.
[5] Gruau's artistic talent in fashion illustration merited him publication at the age of 14 and by the time he reached 18, he was published internationally, in the US, Italy, and France.
Gruau was hired by major designers like Pierre Balmain, Christian Dior, Jacques Fath, Balenciaga, Elsa Schiaparelli, Rochas, Lanvin, Elizabeth Arden, and Hubert de Givenchy.
Gruau, whose posters often echoed both classical Japanese drawings and Toulouse-Lautrec's sketches of fin de siècle Paris night life, was perhaps best known for creating the marketing images for Miss Dior perfume and for Rouge Baiser lipstick.
[4] Because the technical age of the 20th century had yet to emerge, Gruau's pictures were the advertisements of the time and gave marketing and presentation of clothing a new brilliant flair.
[14] His advertising campaigns for Moulin Rouge and Le Lido utilised an old-world aesthetic, celebrating the traditional poster-art graphics of Toulouse-Lautrec, Bonnard and the pre-1900 Parisian artists.
[15] Rene Gruau’s style combines an influence of Japanese woodblock prints and the simplified forms of Toulouse Lautrec with a bright and lively color palette.
