Hugh Lofting
Until the mid-1940s Lenski continued to illustrate other authors' books as well as her own, working with writers including Maud Hart Lovelace, Watty Piper, and Hugh Lofting. However, her biographer Bobbie Malone notes that while Lenski wrote about her work as an illustrator in the 1920s in her autobiography, she did not mention her later work of this type, even on "landmark" books like Piper's "Little Engine" and Lovelace's "Betsy-Tacy" books.
