Mrs. Gardner sat for Sargent during his visit to Boston in January 1888. He was paid $3000 for the portrait, which was exhibited to great acclaim at Boston’s St. Botolph Club. The work also inspired gossip and legend: someone jokingly titled it “Woman: An Enigma,” while others believed that the sensuous display of flesh deliberately echoed the scandal recently created by Sargent’s Madame X.
