This lot includes two illustrated books by Johanna Spyri, Heidi and Heidi Grows Up. The books were published in the USA in 1933 and 1938. The hardcover books are in their original form and are written in English. They both belong to the Children's literature category with a topic that revolves around the adventures of a young girl in the Alp Mountains. They are a great addition for those interested in antiquarian and collectible books, especially for those who are fans of the Heidi character family. Please see pictures for conditions.
