My Digital Drawing of a Tiger (Media: Illustrator)
A floral painting by the late US artist Georgia O'Keeffe has sold for $44.4m (£28.8m) at auction, setting a record for an artwork by a female artist.
The piece smashes the previous record of $11.9m (£7.5m) for an untitled work by Joan Mitchell, set in May.
Sotheby's in New York said the $15m (£9.5m) estimate on O'Keeffe's work was shattered after an intense bidding war between two rivals.
The art auction record is $142.4m (£90.8m) for a Francis Bacon piece.
The British artist's triptych, Three Studies of Lucien Freud, was sold at auction last year.
O'Keeffe, who died in 1986 at the age of 98, was celebrated for her large-format depictions of flowers which she painted as if they had been seen in close-up.
