A major theme of the book is education during the slave period in the United States, which is explored through Little Eva's portrayal as an educator. This version of the character was introduced in an Uncle Tom's Cabin illustration, and popularized by artists and children's literature writers, such as Cozans. The book has also been the subject of academic analysis for its proslavery message, although one scholar described it as an "embattled text" with an "abolitionist impetus".[3]
