Maxwell illustrated multiple books and magazine serials for Pearl S. Buck for over a decade, including the portrait of the author's mother for the cover of the 1935 book, "The Exile", and the companion portrait of her father for the cover of her 1936 book, "Fighting Angel" in addition to his illustrations of the serialized editions of these two books in "Woman's Home Companion" from 1935-1937. Mrs. Buck was the first American woman to be awarded both the Pulitzer Prize (1932) and Nobel Prize (1938) for literature, and these book illustrations are encased along with Buck's Nobel Prize in a glass case at the Green Hills Farm in Perkasie, Pennsylvania.
