Background: O'Keeffe was born on November 15, 1887, in a farmhouse located at 2405 Hwy T in the town of Sun Prairie, Wisconsin. Her parents, Francis Calyxtus O'Keeffe and Ida (Totto) O'Keeffe, were dairy farmers. Her father was of Irish descent. Her maternal grandfather George Victor Totto, for whom O'Keeffe was named, was a Hungarian count who came to the United States in 1848.
Context: O'Keeffe was a legend beginning in the 1920s, known as much for her independent spirit and female role model, as for her dramatic and innovative works of art. Nancy and Jules Heller said, "The most remarkable thing about O'Keefe was the audacity and uniqueness of her early work." At that time, even in Europe, there were few arts exploring abstraction. Even though her works may show elements of different modernist movements, such as Surrealism and Precisionism, her work is uniquely her own style. She received unprecedented acceptance as a woman artist from the fine art world due to her powerful graphic images and within a decade of moving to New York City, she was the highest paid American woman artist. She was known for a distinctive style in all aspects of her life. O'Keeffe was also known for her relationship with Stieglitz, in which she provided some insight in her autobiography.  A substantial part of her estate's assets were transferred to the Georgia O'Keeffe Foundation, a nonprofit. The Georgia O'Keeffe Museum opened in Santa Fe in 1997. The assets included a large body of her work, photographs, archival materials, and her Abiquiu house, library, and property. The Georgia O'Keeffe Home and Studio in Abiquiu was designated a National Historic Landmark in 1998 and is now owned by the Georgia O'Keeffe Museum.  In 1996, the U.S. Postal Service issued a 32 cent stamp honoring O'Keeffe. In 2013, on the 100th anniversary of the Armory Show, the USPS issued a stamp featuring O'Keeffe's Black Mesa Landscape, New Mexico/Out Back of Marie's II, 1930 as part of their Modern Art in America series.  A fossilized species of archosaur was named Effigia okeeffeae ("O'Keeffe's Ghost") in January 2006, "in honor of Georgia O'Keeffe for her numerous paintings of the badlands at Ghost Ranch and her interest in the Coelophysis Quarry when it was discovered".  O'Keeffe holds the record ($44.4 million in 2014) for the highest price paid for a painting by a woman.
Question: What was her most famous work of art
Answer: 

Background: Eleanora Fagan (April 7, 1915 - July 17, 1959), better known as Billie Holiday, was an American jazz musician and singer-songwriter with a career spanning nearly thirty years. Nicknamed "Lady Day" by her friend and music partner Lester Young, Holiday had a seminal influence on jazz music and pop singing. Her vocal style, strongly inspired by jazz instrumentalists, pioneered a new way of manipulating phrasing and tempo. She was known for her vocal delivery and improvisational skills, which made up for her limited range and lack of formal music education.
Context: In 1935 Holiday was signed to Brunswick Records by John Hammond to record current pop tunes with Teddy Wilson in the new swing style for the growing jukebox trade. They were given free rein to improvise the material. Holiday's improvisation of melody to fit the emotion was revolutionary. Their first collaboration included "What a Little Moonlight Can Do" and "Miss Brown to You". "What a Little Moonlight Can Do" has been deemed her "claim to fame." Brunswick did not favor the recording session, because producers wanted Holiday to sound more like Cleo Brown. After "What a Little Moonlight Can Do" garnered success, however, the company began considering Holiday an artist in her own right. She began recording under her own name a year later (on the 35-cent Vocalion label), producing a series of extraordinary performances with groups comprising the swing era's finest musicians. The sessions were co-produced by Hammond and Bernie Hanighen.  With their arrangements, Wilson and Holiday took pedestrian pop tunes, such as "Twenty-Four Hours a Day" (number 6 Pop) and "Yankee Doodle Went to Town", and turned them into jazz classics. Most of Holiday's recordings with Wilson or under her own name during the 1930s and early 1940s are regarded as important parts of the jazz vocal library. She was then in her twenties.  Another frequent accompanist was the tenor saxophonist Lester Young, who had been a boarder at her mother's house in 1934 and with whom Holiday had a special rapport. He said, "I think you can hear that on some of the old records, you know. Some time I'd sit down and listen to 'em myself, and it sound like two of the same voices, if you don't be careful, you know, or the same mind, or something like that." Young nicknamed her "Lady Day", and she called him "Prez".  Hammond spoke about the commercial impact of the Wilson-Holiday sides from 1935 to 1938, calling them a great asset to Brunswick. The record label, according to Hammond, was broke and unable to record many jazz tunes. Wilson, Holiday, Young, and other musicians came into the studio without musical arrangements and improvised as they performed, dispensing with the expense of having written arrangements, so that the records they produced were cheap. Holiday was never given any royalties for her work, instead being paid a flat fee, which saved the company money. Some of the records produced were successful, such as "I Cried for You", which sold 15,000 copies. Hammond said of the record, "15,000 ... was a giant hit for Brunswick in those days. I mean a giant hit. Most records that made money sold around three to four thousand."
