Eloise (originally titled Eloise: A Book for Precocious Grown-ups) is the first of the Eloise book series written and drawn by Kay Thompson and Hilary Knight, respectively. It was published in 1955. In 1969, the adult-oriented book was re-released as a children's book, without change. An audiobook version of Eloise, narrated by Bernadette Peters, was released in October 2015 to coincide with the 60th anniversary of the series. The title character was inspired by an alter ego of Thompson. Source: Wikipedia (en)
