Judith Leyster's 400th birthday will be celebrated at the National Gallery of Art with an exhibition of ten of her most engaging paintings, joined by some 20 works by 17th-century contemporaries, including her presumed teacher Frans Hals and her husband Jan Miense Molenaer, as well as musical instruments of the period depicted in the art. 'Judith Leyster, 1609–1660' will be on view from June 21 through November 29, 2009, in the Dutch Cabinet Galleries in the Gallery's West Building.
