This year's art calendar is packed with major exhibitions, including a large-scale Marcel Duchamp retrospective at MoMA in New York, and two shows featuring Zurbarán and portraits by Jan van Eyck at the National Gallery in London. The list of big names, both Catalan and international, continues with Aurèlia Muñoz, Richard Avedon, and Matisse. Meanwhile, Barcelona, as UNESCO's World Capital of Architecture, will host around fifty exhibitions.
