how much is the painting a sunday afternoon on the island of la grande jatte
Seurat’s first major pointillist work was Bathers at Asnieres (1883-4, National Gallery, London). Although rejected by the official Paris Salon, the work was shown at the Salon des Independants, an alternative event co-founded by Seurat himself, where he met fellow pointillists Paul Signac (1863-1935) and Henri-Edmond Cross (1856-1910), who helped him to further develop the idiom. Shortly afterwards Seurat began painting A Sunday Afternoon on the Island of La Grande Jatte, which took him two years to finish. It was exhibited for the first time in May 1886 at the final Impressionist exhibition: an ironic occurrence since the work is now seen as one of the first major examples of Post-Impressionist painting (1880-95).
The huge work (7 feet in height; 10 feet in width) caused a sensation. Not only did it exude a shimmering impression of warm, hazy sunshine, but the stylized, statuesque nature of its figure painting exuded a timeless and monumental quality. Unlike the fleeting naturalism of Monet (1840-1926) and Renoir (1841-1919), which captured the momentary perceptions of the artist, La Grande Jatte was painstakingly planned from start to finish in the manner of a Greek frieze, and its (often) symbolic content positively invites careful scrutiny.
The painting and the life of its artist were the basis for the 1984 Broadway musical Sunday in the Park with George by Stephen Sondheim and James Lapine. Subsequently, the painting is sometimes referred to by the misnomer “Sunday in the Park”.
In 1923, Frederic Bartlett was appointed trustee of the Art Institute of Chicago. He and his second wife, Helen Birch Bartlett, loaned their collection of French Post-Impressionist and Modernist art to the museum. It was Mrs. Bartlett who had an interest in French and avant-garde artists and influenced her husband’s collecting tastes. Sunday Afternoon on the Island of La Grande Jatte was purchased on the advice of the Art Institute of Chicago’s curatorial staff in 1924.

What makes this painting even more unique and mysterious is that the theme of the work is not some profound emotion or momentous event, but the banalest of workaday scenes.
Seurat’s use of this highly systematic and near-scientific technique  distinguished his art from the endlessly more intuitive approach to painting used by the Impressionists. Georges may have embraced the subject matter of modern life preferred by artists such as Claude Monet and Pierre-Auguste Renoir, but the way he depicted it on canvas couldn’t be any more different from the techniques of his peers.
Dalí occasionally moonlighted as a fashion designer, bringing some of his signature motifs to womenswear. He collaborated with Italian fashion designer Elsa Schiaparelli to create clothing inspired by his paintings, like a dress with drawer-like pockets inspired by The Anthropomorphic Cabinet, a shoe hat inspired by a photo Dalí took of Gala, and a lobster-print dress worn by Wallis Simpson in a Vogue photoshoot in 1937. (Dalí regularly put lobsters in his paintings, often using them to represent his fear of castration.)
Not just Seurat’s most popular piece, but also his biggest, A Sunday on La Grande Jatte —1884 measures in at 81 3/4 inches by 121 1/4 inches, or about 7 feet by 10 feet. Its large size makes its every inch flush with tiny dots of color all the more remarkable.
