NEW YORK — What's a selfie worth?

If they're from Andy Warhol, made with a silkscreen rather than a smart phone, the answer is millions.

A series of six of the eccentric American artist's self-portraits sold at auction Wednesday in New York for $30.1 million.

Warhol made the vibrant images of himself wearing his famous “fright wig” in 1986 — a year before his death and just over a quarter-century before the Oxford English Dictionary made the suddenly ubiquitous “selfie” its word of the year.

Warhol's trailblazing, if not technologically parallel, take led the bidding at Sotheby's contemporary art auction and capped a triumphant week for his work.

The artist's 1960s work “Big Electric Chair,” which shows an execution chamber against panels of blue, green and pink fetched $20.4 million at the same Sotheby's auction. His “12 Mona Lisas” went for $11.4 million.

Two other works from Warhol's “Death and Disaster” series sold Tuesday at Christie's for a combined $100 million.

Warhol's “Race Riot, 1964” — a provocative four-panel painting of unrest in Birmingham, Alabama — went for $62.9 million at Christie's auction of postwar and contemporary works, far exceeding the estimate of $45 million.

The work was a direct response to an article Warhol saw in Life magazine that ran with an image by Associated Press photographer Charles Moore.

Warhol's 1962 painting “White Marilyn,” completed shortly after Hollywood star Marilyn Monroe took her life, sold for $41 million, well above its estimate of $12 million to $18 million.All prices included the buyer's premium.German painter Gerhard Richter's “Blau” sold Wednesday for $28.7 million, about $9 million shy of his auction record set last year at Sotheby's.Jeff Koons' 7-foot-tall stainless steel sculpture of the spinach-loving cartoon character “Popeye” went for $28.2 million. His “Jim Beam J.B. Turner Train,” a 9½ -foot-long-stainless steel sculpture filled with bourbon, sold Tuesday for $33.8 million.
