"Andrew Wyeth: Looking Out, Looking In" now at the National Gallery until November 30, 2014. Call this show a retrospective of Wyeth's love of windows centered around his work Wind from the Sea. So, yes be prepared for room after room of moody atmospheric paintings of windows. What you are really looking for are the little moments - the gnarled wood of a window frame, the lines of leafless branches, the rough surface of stone, the winter light. It's a beautiful show...just a lot of windows.
