It's probably one of the most widely-known and easily-recognized paintings in the Art Institute's collection. And tomorrow it's the centerpiece of the museum's new exhibition, Seurat and the Making of La Grande Jatte. Early Seurat works will be featured, as will pieces by artists that inspired Seurat. But the main feature will of course be the 1884 painting A Sunday on La Gande Jatte. Researchers have put together an alternate color-corrected version of the painting that supposedly represents how the painting appeared when it was first unveiled. This alternate version hasn't been shown to the press, so you have to go to the exhibit to see it. The exhibit runs from June 19 through September 19.
