Details: This poster is of Sunday Afternoon on the Island of La Grande Jatte, by Georges Seurat. It shows members of each of the social classes participating in various park activities. An example of pointilism, the tiny juxtaposed dots of multi-colored paint allow the viewer's eye to blend colors optically, rather than having the colors blended on the canvas or pre-blended as a material pigment.
Georges-Pierre Seurat (2 December 1859 – 29 March 1891) was a French Post-Impressionist painter and draftsman. His large work A Sunday Afternoon on the Island of La Grande Jatte (1884–1886), his most famous painting, altered the direction of modern art by initiating Neo-impressionism, and is one of the icons of 19th century painting.
