NEW YORK, DEC. 3 -- Eleven Georgia O'Keeffe paintings sold for nearly $9 million and two Edward Hopper paintings brought $3.6 million today at an auction at Sotheby's that brought in a total of $37.3 million, a record for a sale of American paintings.

The sale, one of the largest-ever offerings of its kind, encompassed nearly 400 works by such artists as James McNeill Whistler, Albert Bierstadt, Stuart Davis, Andrew Wyeth, Winslow Homer and Frederic Remington. It almost doubled the previous record of $19 million for an auction of American paintings.

O'Keeffe's "Black Hollyhock With Blue Larkspur" went for $1.95 million, an auction record for an O'Keeffe. It and eight other O'Keeffes were sold by Anita O'Keeffe Young, the artist's sister, to Gerald Peters, an art dealer from Santa Fe.

The paintings ranged in date from 1924 to 1954 and represented some of O'Keeffe's first efforts at her "big flower" series.

Hopper's "Captain Upton's House" sold for a record $2.31 million.

The auction also included Martin Johnson Heade's "Two Fighting Hummingbirds With Two Orchids," which sold to an anonymous buyer for $1.93 million, a record for Heade.
