This is a small detail of another painting in the collection of the Spencer Museum of Art, University of Kansas. The painting, done sometime between 1610 and 1628, is a portrait of Maria Maddalena, Grand Duchess of Tuscany and Archduchess of Austria. The duchess and her mother-in-law ruled Tuscany as co-regents for several years after the death of Cosimo II de Medici. In this detail I especially like the exquisite depiction of the lace bordering the handkerchief.
