Last Friday, a portrait produced by artificial intelligence was hanging at Christie’s New York opposite an Andy Warhol print and beside a bronze work by Roy Lichtenstein. On Thursday, it sold for well over double the price realized by both those pieces combined.

“Edmond de Belamy, from La Famille de Belamy” sold for $432,500 including fees, over 40 times Christie’s initial estimate of $7,000-$10,000. The buyer was an anonymous phone bidder.

The bidding late this morning lasted just under seven minutes, during which the buyer competed against an online bidder in France, two other phone bidders and one person in the room in New York. When the hammer came down, the bids had reached $350,000, the final price before fees.

The distorted portrait, by the French art collective Obvious, was marketed by Christie’s as the first portrait generated by an algorithm to come up for auction.
