The Metropolitan Museum of Art (The Met) in New York is currently holding a Seurat Circus Sideshow (en exhibition devoted to Seurat).
The Web resource Artsy, dedicated to making works of art accessible to anyone with an internet connection, has a page on Seurat and invited The Normandy Photo Journal (see this post about Seurat and Port-en-Bessin) to share and publicise it. Reading Art is also invites its readers to have a look.
Thanks, Artsy! This is Seurat's most famous work 'A Sunday Afternoon on the Island of L Grande Jatte' (Un dimanche après-midi à l'île de la Grande Jatte), 1884, a masterpiece of the technique known as pointillism (painting by small colour points).
