The National Gallery of Art unveils a show of artwork from one of America's best known painters, Andrew Wyeth, on May 4th that has a decidedly new twist. The exhibit focuses on Wyeth’s fascination with windows – an apparently unnoticed feature of his work that came to light when a curator began wondering about a Wyeth acquisition that came to the gallery in 2009.

The evocative painting of a window with gently billowing curtains and a landscape through the window, “Wind from the Sea,” made curator Nancy K. Anderson start looking for more. “Are we making this up?” she asked, only to have Wyeth family members confirm his interest in windows.
