From the publisher:

Millions of viewers have enjoyed Saludos Amigos and The Three Caballeros without realizing that these Disney films were produced for a specific diplomatic purpose as part of an initiative to foster a spirit of friendly hemispheric unity: The Good Neighbor Program. Based on extraordinarily comprehensive archival research and richly illustrated with many images never before published, South of the Border with Disney: Walt Disney and the Good Neighbor Program (1941-1948)--authored by JB Kaufman--is a fascinating study of an all but forgotten aspect of the American war effort.

This came from the library of Burny Mattinson (1935-2023), an animator, director, producer, and story artist for Walt Disney Animation Studios, from 1953 until his death in 2023. Mattinson directed Mickey's Christmas Carol and The Great Mouse Detective. He was named a Disney Legend in 2008 and was the longest serving employee of The Walt Disney Company, with a career that spanned almost 70 years. His extensive library included numerous subjects and especially large collections of books on Disney, animation, and classic comic strips.
