Artis Frida Kahlo's painting 'Nina Con Collar' sits on an easel at Sotheby's auction house in New York.
NEW YORK - Mexican artist Frida Kahlo's "Nina con Collar," an early painting whose whereabouts had been a mystery for 60 years, has sold for $1.81 million(R25.68 million) at a Sotheby's Latin American art auction.
Works by Mexican Rufino Tamayo and Colombia's Fernando Botero topped sales at the auction.
"We saw a series of exceptional prices for the giants of Latin American modern art," said Axel Stein, Sotheby's Latin American art chief, commenting on the $16.84 million in total sales on Tuesday evening in New York.
Leading the sale was Tamayo's "Sandas y naranja" (Watermelons and orange), a 1957 oil and sand on canvas once owned by film star Audrey Hepburn, Sotheby's said. It sold for $2.29 million.
A Botero bronze sculpture, "Man on a Horse," fetched $1.82 million, and his "Homage to Bonnard," a large-scale nude painting, went for $1.39 million.
Kahlo's "Nina con Collar," (Girl with Necklace), which had not been seen publicly for six decades, went to an unidentified European buyer. The 1929 oil on canvas is among the first 20 of the Mexican artist's 143 paintings, Stein said.
The work, whose subject is about 13 or 14, prefigures hallmarks of Kahlo's self-portraits, including winged eyebrows and a full frontal gaze.
Kahlo died at age 47 in 1954. The following year, her widower, the muralist Diego Rivera, gave "Nina con Collar" to one of her studio assistants, who hung it in her California home for 60 years, according to Stein.
The work came to light when the unidentified former studio assistant, now in her mid-90s, contacted Sotheby's last summer, Stein said.
In international art markets, works by Kahlo have fetched more than any other Latin American artist, according to Stein.
Last May, Christie's sold a 1939 Kahlo painting for $8 million, an auction record for her work.
Sotheby's has privately sold Kahlo works for more than $15 million each, said Dan Abernethy, an auction house spokesperson.
One reason Kahlo's works are so valued in the international market is that Mexico barred their export for several decades under laws to conserve the country's cultural heritage, Stein said.
