“Manifest Destiny,” one of the showstoppers in the current exhibition “Alexis Rockman: a Fable for Tomorrow,” will become a permanent part of the Smithsonian American Art Museum collection.

The painting, explained the museum, will be a provocative compliment to the museum’s collection of 19th century landscapes. The purchase is the first Rockman in the permanent archives.

The Rockman show, a survey of his work from the mid-198s to the present, closes on Sunday and will travel to the Wexner Center for the Arts in Columbus, Ohio. “Manifest Destiny” will go along for the show. Then the painting, originally commissioned by the Brooklyn Museum of Art, will return to Washington.

Here is a gallery of Rockman’s work, prepared by the Washington Post graphics department.
