Curators at the College of William and Mary are recreating a little-known exhibition of paintings by Georgia OKeeffe held at the school for six days in 1938. OKeeffe, who lived in Williamsburg as a teenager, returned to the town that year to accept an honorary degree. She and her husband and manager, Alfred Stieglitz, agreed to mount a small exhibit, which in turn was the first showing of OKeeffes works in the South. Exhibit planners Bonnie Kelm (W&M) and Ann Madonia (W&M) say a recently discovered 6 minute film of OKeeffe receiving her honorary degree should help dispel myths that the homecoming was an unhappy time for the artist.
