Smiling Girl
The Smiling Girl, formerly thought to be by Johannes Vermeer, was donated by collector Andrew W. Mellon in 1937 to the National [Gallery of Art] in Washington, D.C. Now widely considered to be a fake, the painting was deemed by the Vermeer expert Arthur K. [Wheelock Jr.] in a 1995 study to be by a 20th-century artist and forger, Theo [van Wijngaarden], a friend of Han van Meegeren.
