This weekend, visitors to the Crystal Bridges Museum of American Art in Bentonville, Arkansas, will be able to view the most expensive work of art ever painted by a woman.  It is Georgia O’Keeffe’s “Jimson Weed/White Flower No. 1”.  It goes on display Saturday at the museum founded and funded by Walmart heiress Alice Walton.  Walton paid $44.4 million for the 1932 portrait at a Sotheby’s auction in November. The artwork goes on display as the centerpiece of the “See What I See” exhibition that runs through May 10.  For the past 15 years, Walton has been responsible for setting records in the “American Art” field, snapping up some of the greatest works in that category. Ironically, she has singlehandedly inflated the sector which has made her subsequent purchases more expensive.
