This full-length portrait of the Infanta Maria, the future queen of Hungary and Bohemia, daughter of Philip III and Margarita of Austria and sister to Philip IV, is likely to have been painted in the 1620s by a close follower of Juan van der Hamen. The pose of the Infanta, and the composition as a whole, is closely related to several full length portraits of members of the royal family tentatively given to Van der Hamen (1596–1631) by William B. Jordan.1
