A visit to the American Impressionism exhibition currently on at The Scottish National Gallery of Modern Art is recommended if you are drawn to Mary Cassatt and John Singer Sargent, for example, and Monet, Degas, Berthe Morisot and others whose work influenced them.
Lady Agnew is there (and do listen to the curator, Frances Fowle's brief podcast - no. 12 - or watch her video on that work), and alongside her is the painting shown here: Sita and Sarita by Cecilia Beaux, "a stunning exercise in flamboyant technique," of which you can read more here.
