A painting by British pop-artist David Hockney is expected to smash records for most expensive work by a living artist when it goes up for auction at Christie’s in New York in November, the auction house announced Thursday.

The 80-year-old Hockney’s “Portrait of an Artist (Pool with two figures)” is expected to fetch $80 million when it goes under the hammer — that’s $22 million more than the reigning record of $58.4 million set by Jeff Koons’ “Balloon Dog (Orange)” in 2013.

Alex Rotter, Christie’s co-chairman of postwar and contemporary art, called the painting “one of the great masterpieces of the modern era.”

The 1972 acrylic-on-canvas depicts a man — modeled after Hockney’s former lover and muse Peter Schlesinger — peering down into a swimming pool where a second figure is doing an underwater breaststroke.

The painting dates back to the year that Hockney and Schlesinger split, and the swimmer may have represented Schlesinger’s new lover.

“David Hockney’s brilliance as an artist is on full display with this monumental canvas, which encapsulates the essence of the idealized poolside landscape, and the tremendous complexity that exists within human relationships,” Rotter said in a statement. “With this painting, Hockney cemented his placement within the realm of history’s most venerated artists.”

The setting depicts a pool at film director Tony Richardson’s French hamlet Le Nid-du-Duc, and features the verdant, rolling hills of Saint-Tropez.

The painting will go up for auction on Nov. 15 in New York.
