It was one of two works that Tissot submitted to the Salon of 1864 along with The Two Sisters, which featured the same model who appeared in this picture. Today the painting is in the collection of the Musée d'Orsay in Paris having been acquired by the French state in 1907.https://pop.culture.gouv.fr/notice/joconde/000PE002613
