In 1927, Lempicka won her first major award, the first prize at the Exposition Internationale des Beaux Arts in Bordeaux, France, for her portrait of Kizette on the Balcony. In 1929, another portrait of Kizette, at her First Communion, won a bronze medal at the international exposition in Poznań, Poland. In 1928 she was divorced from Tadeusz Łempicki. That same year, she met Raoul Kuffner, a baron of the former Austro-Hungarian Empire and an art collector. His title was not an ancient one; his family had been granted the title by the second-to-last Austro-Hungarian Emperor, Franz-Joseph I, because Kuffner's family had been the supplier of beef and beer to the imperial court. He owned properties of considerable size in eastern Europe. He commissioned her to paint his mistress, the Spanish dancer Nana de Herrera. Lempicka finished the portrait (which was not very flattering to de Herrera) and took the place of de Herrera as the mistress of the baron. She bought an apartment on rue Méchain in Paris and had it decorated by the modernist architect Robert Mallet-Stevens and her sister Adrienne de Montaut. The furniture was by Rene Herbst. The austere, functional interiors appeared in decoration magazines.
