A highly anticipated Philip Guston retrospective conceived by curators at the National Gallery of Art in Washington, D.C., the Museum of Fine Arts Boston, the Museum of Fine Arts Houston, and London’s Tate Modern has been pushed back four years amid concerns by the museums’ directors over the Ku Klux Klan imagery that recurs throughout the American painter’s oeuvre, particularly his later works. The decision has sparked outrage among some scholars, curators, and critics, who say that the museums have not only betrayed a lack of faith in their viewerships but have also missed an opportunity to engage with the very issues being invoked as reasons to postpone the exhibition.
