The tree sat on the Kiowa Ranch, a property that noted arts patron Mabel Dodge Luhan had given to Frieda Lawrence, wife of the British writer D.H. Lawrence, in 1924 in exchange for the manuscript of his novel “Sons and Lovers.” “The Lawrence Tree” is a beautifully crafted painting. Trunk, branches, leaves and night sky form an intricate pattern, creating the taut balance between image and abstract form that O’Keeffe was achieving in many of her paintings of the 1920s.
