finding a Georgia

I walked through the Indianapolis Museum of Art last week, snapping pictures as I went:

I paused and thought, Is that a Georgia O'Keeffe? I drew closer and realized that indeed it is:

It's Jimson Weed, created between 1936 and 1937. The accompanying plaque reads:

This is O'Keeffe's largest and most amibitious floral work, with her signature emphasis on size and contour. In 1936 Elizabeth Arden commissioned O'Keeffe to paint Jimson Weed for the exercise room of her New York spa.

Who was Elizabeth Arden? Most women should know.
