I recently discovered the Marmottan Monet museum in Paris, a great place for impressionists such as Berthe Morisot, Pissaro, Renoir, Sisley, and ... Monet. There is also an interesting collection of illuminations, but I don't know much aboute these.
You have until Frebruary 2012 to admire the new exhibition : Henri Edmond Cross and Neo-impressionism, from Seurat to Matisse.
Mr Cross being a friend of Paul Signac, and given my new crush on neo-impressionism, I could barely wait for the exhibition to open.
