A group of leading artists, artist estates, collectors, and dealer has donated 25 works of art to benefit the Whitney Museum of American Art’s new Renzo Piano-designed building in downtown Manhattan. The works, which are said to be worth upward of $8 million, will be put up for auction at Sotheby’s New York from May 14-15, 2013.

All of the artists involved in the multifaceted gift have strong ties to the Whitney and are represented in the museum’s stellar permanent collection. The most valuable work that will be up for auction in May is Jasper Johns’ (b. 1930) oil on canvas painting Untitled (2012), which is estimated to sell for $1.5 million to $2 million. Johns has had five solo shows at the Whitney and has participated in over 37 group exhibitions; the donation came directly from the artist. Other highlights from the sale include a Jeff Koons (b. 1955) silkscreen on stainless steel, a Cy Twombly (1928-2011) work on paper, a recent nude by John Currin (b. 1962), and other works by John Baldessari (b. 1931), Andy Warhol (1928-1987), and Ed Ruscha (b. 1937).    

All of the profits from the sale will directly benefit the Whitney’s new building, which is expected to open in the High Line District in 2015.
