ART

An Henri Matisse painting not seen in public for more than 50 years went on view Wednesday at the National Gallery of Art’s exhibition “Henri Matisse: The Early Years in Nice, 1916-1930” in Washington. The painting, “La Toque de Velours Bleu” (“The Blue Velour Hat”) features Matisse’s daughter Marguerite. It was last seen in Switzerland in 1931 and had been presumed lost until it surfaced recently at the Norton Gallery of Art in West Palm Beach, Fla.
