Masterworks by Jean-Michel Basquiat and Vija Celmin on offer at Sotheby's marquee New York sale

Basquiat's "Untitled (Head)" and Celmins' "Night Sky #7" will go under the hammer during the house's Contemporary Art Evening Sale, which will be livestreamed from London on June 29.

Sotheby's has now announced new additions to the sale's catalogue, including pieces by the likes of Jean-Michel Basquiat, Vija Celmins and Donald Judd.

"Untitled (Head)" is an example of Jean-Michel Basquiat's revered corpus of works on paper, which the American artist held in his private collection until his untimely death in 1988.

Bearing close resemblance to the seminal "Untitled" from 1981, this masterwork was exhibited in 1990 in the storied Robert Miller Gallery presentation of Basquiat's drawings.

"‘Untitled (Head)' encapsulates the very best of Basquiat's brilliant career. There is a sense of urgency and immediacy in this work that is truly exceptional -- a prescient piece that captures and defines 1980s New York, and demonstrates the young artist's profound psychological awareness," Grégoire Billault, Head of Sotheby's Contemporary Art Department in New York, said in a statement.

"Untitled (Head)" is now hitting the auction block at Sotheby's London, where it is estimated to sell for between $9 million and $12 million.

Also on offer is the largest painting by Celmins to ever appear at auction, entitled "Night Sky #7."

As one of the Latvian-American artist's most emblematic works, "Night Sky #7" was notably included in her 2019 retrospective at the Metropolitan Museum of Art in New York City.

The large-scale canvas is expected to fetch up to $8 million, potentially establishing a new auction record for Celmins.

Her current record price was set in November 2018, when "Lead Sea #2" sold well above its high pre-sale estimate of $2.5 million and realized $4.2 million at Christie's.

"It is exceedingly rare to find a painting on canvas by Vija Celmins of this caliber and scale in private hands, given the extremely limited scale of her production, with the vast majority of her Night Sky paintings in museum collections worldwide," David Galperin, Head of Sotheby's Evening Auctions of Contemporary Art in New York, said of the upcoming sale.

The latest addition to the catalogue of Sotheby's marquee New York sale is Donald Judd's very first three-dimensional wall relief, entitled "Untitled (DSS 25)."

"Untitled (DSS 25)" testifies to the American Minimalist artist's radical shift into dimensionality, with three additional variations on the work on offer currently held in the collections of the Kunstmuseum Basel, Judd Foundation and the Fondazione Prada.

Last seen on the market in 1963, the masterpiece is estimated to go under the hammer for between $4 million and $6 million.

These pre-sale estimates are far from those of Francis Bacon's 1981 three-part oil painting, "Triptych Inspired by the Oresteia of Aeschylus," which is estimated to realize over $60 million during Sotheby's Contemporary Art Evening Sale.
