August Art Roundup: Signac in Potsdam, Kahlo in London, and More

The August 2026 art calendar is packed with major exhibitions across Europe. In Potsdam, the Museum Barberini presents 'Symphonie der Farben. Paul Signac und der Neoimpressionismus', the first comprehensive German show of the Pointillist in thirty years, featuring works by Signac and contemporaries such as Henri-Edmond Cross, Anna Boch, and Maximilien Luce. In London, the Tate Modern hosts 'Frida: The Making of an Icon', previously at the Museum of Fine Arts in Houston, with 30 original works, personal objects, and over 200 contemporary pieces. The Kunst Museum Winterthur opens 'Zur Sonne! Zur Freiheit!', curated by David Schmidhauser and Florian Illies, focusing on open-air painting around 1800, including works by Carl Blechen and Camille Corot, with a first-time emphasis on Swiss developments. Vienna's Unteres Belvedere presents the first Austrian show of Erna Rosenstein (1913–2004), a key figure of the Polish post-war avant-garde, with 80 works. The Museum Frieder Burda in Baden-Baden features Simon Hantaï, known for his 'pliage comme méthode' technique, and the Hamburger Kunsthalle pairs Maria Lassnig and Edvard Munch in a double exhibition exploring existential themes. The auction market saw notable results: Henri Matisse's 'La Chaise lorraine' fetched $41.5 million at Sotheby's New York, Carla Accardi's double-sided painting sold for €400,000 at Dorotheum, and Constantin Brancusi's 'Danaïde' achieved a record $93 million at Christie's.
