Original works from 25 artists coming to auction are estimated to bring in more than $8 million to support the construction of a new building for the Whitney Museum of American Art in New York City.
Sotheby's says Friday original paintings from artists like Jasper Johns, Cy Twombly and Ellsworth Kelly have been donated by the artists, artists' estates, private collectors and dealers.
A 2012 Jasper Johns work called "Untitled'' is estimated to bring in as much as $2 million alone.
The auction will be held on May 14 and 15 at Sotheby's.
The museum's new building is projected to open in 2015 and will have three times more gallery space. The designer is Italian architect Renzo Piano.
