1887, Paul Cezanne, Madame Cezanne in Blue -- National Gallery of Art (Washington) (special exhibition)

From the exhibition label: The wallpaper with a teardrop pattern seen in these three related paintings (as well as two others in the next room) indicates these works were painted in the Cézanne family estate in Aix. The wooden shape behind Madame Cézanne at left is the side of a carved piece of furniture.
