For which company did Georgia O'Keeffe paint a 1939 series after visiting Hawaii?

Georgia O'Keeffe painted a 1939 series for the Hawaiian Pineapple Company.

The company, now associated with the Dole Food Company, invited O'Keeffe to Hawaii in 1939 to create images for an advertising campaign. During the trip she visited several islands and painted tropical flowers, plants, landscapes, and other subjects. The assignment was unusual because it connected a major modernist painter with commercial promotion.

O'Keeffe did not initially paint the pineapple the company expected. After being asked for a pineapple image, she later painted one when the fruit was sent to her in New York. The resulting works were exhibited in Honolulu and New York. The trip expanded the geographic range of her subject matter, but it did not displace New Mexico as the central landscape of her later career.
