Christo, the artist who has wrapped buildings, lined drapes along highways and hung orange panels in Central Park, is donating two preparatory collages of his next project to the National Gallery of Art.

Plan for "Over the River" by Christo (By Andre Grossman/ Cristo 2010)

The gallery, according to a spokeswoman, will exhibit the new gifts along with four other Christo works in the lobby of the East Building auditorium beginning Tuesday.

In 2002 the gallery exhibited 61 objects of Christo and his late artistic partner and wife, Jeanne-Claude, for 5 months. The work covered more than 40 years of their careers and was part of the acquisition by the museum of the collection of Dorothy and Herbert Vogel.

The gallery has nearly 80 works of Christo and Jeanne-Claude, ranging from drawings to photographs to sculpture.

In 2010 the Smithsonian American Art Museum presented a detailed show about an early project in Northern California that covered 24.5 miles called “The Running Fence.”

The new gifts at the National Gallery will be on display through January 23.
