The art of French Neo-Impressionist painter Paul Signac is in high demand. So much so that, in May of last year, his 1915 depiction of the port of La Rochelle, valued at about $1.7 million, was stolen from the Museum of Fine Arts in Nancy, France. (This spring, it was recovered in Ukraine and returned to the museum.) Signac, born in 1863, is best known for his contributions alongside Georges Seurat to the pointillism movement. Throughout his career, Signac also painted watercolors: Lézardrieux, l’Église, painted in Brittany, circa 1929, is on view at Sotheby’s in advance of its sale in the Impressionist and Modern Art Online auction on July 24.
