Dimensions 70 cm x 50 cm 27.5" x 19.5" 1,000 pieces About A Sunday Afternoon on the Island of La Grande Jatte Georges Seurat's masterpiece, A Sunday Afternoon on the Island of La Grande Jatte is a leading example of pointillist technique. It is a founding work of the Neo-Impressionist movement. In his largest painting, Georges Seurat depicts people relaxing in a suburban park on an island in the Seine River called La Grande Jatte. Their stillness is as enigmatic as it is fascinating. Highly criticized and ridiculed when first exhibited in Paris, this painting is now considered Georges Seurat’s greatest work. With scientific precision, he juxtaposed tiny dabs of colors that, through optical blending, form a single and, in his opinion, more brilliantly luminous hue.
