Andrew Wyeth exhibit leaves viewers on the outside looking in at the National Gallery

Visitors to the National Gallery of Art's "Andrew Wyeth: Looking Out, Looking In" are greeted by a masterpiece, the artist's 1947 "Wind from the Sea," which structures the whole exhibition. The theme is windows, their recurrence as icon in the painter's oeuvre, their personal and sometimes hermetic meanings as metaphor, and the larger tension they set up between representation and abstraction in the some 60 paintings, watercolors and drawings on view.
