In 2012, the Rosenberg family identified "Profil bleu devant la cheminée" (Woman in Blue in Front of Fireplace; 1937), a Matisse painting that was confiscated by the Nazis in 1941, in an exhibition catalogue and demanded that the Henie-Onstad Art Centre (HOK) near Oslo, Norway, return it. Rosenberg had bought the painting directly from Matisse in 1937 and had it stored at the time of the Nazi invasion in a bank vault in Libourne, a commune in the Gironde in Aquitaine, southwestern France. The ERR entered the vault in March 1941, and, after cataloging at the Galerie nationale du Jeu de Paume in September 1941, it was earmarked for Göring's private collection. Then in the hands of various dealers during the Nazi period, post-war in the late 1940s it was bought by Norwegian shipping magnate Niels Onstad from the Paris-based dealer Henri Bénézit. It has since appeared in numerous publications and toured the world on several occasions. Although under Norwegian law, due to the period of ownership, the painting now belongs to HOK, Norway was one of 44 signatories to the 1998 Washington Conference Principles on Nazi-Confiscated Art. Protracted mediation, overseen by Christopher A. Marinello of the Art Recovery Group, saw the painting returned to the heirs of Paul Rosenberg in March 2014.
