On today's ST, we are pleased to once again welcome Catherine Whitney, the Chief Curator and Curator of American Art at the Philbrook Museum of Art here in Tulsa, who tells us about a fantastic new show on view at that museum called "New York to New Mexico: Masterworks of American Modernism from the Vilcek Foundation Collection." This show will run through May 3rd; more info can be accessed at the museum's website. Drawn from the Vilcek Foundation Collection in New York City and curated by Whitney herself, this exhibition presents over 50 masterworks of American modernism ranging from the early 20th century to the postwar era. Various media are included -- paintings, sculptures, and works on paper -- and special emphasis is given to American cubism, to the nature-based abstractions of the Stieglitz Circle, and to the regional modernism of the American Southwest. Thus the show features work by such greats as Georgia O'Keeffe, Marsden Hartley, Arthur Dove, Oscar Bluemner, and Stuart Davis.
