"A book on one of the most exciting and colorful phases in the rich cultural history of Mexico." This is how Nelson A. Rockefeller, in 1978, during his last trip to Mexico, described the book he planned to publish about his astonishing collection of Mexican folk art. Folk Treasures of Mexico: The Nelson A. Rockefeller Collection is that book, and Rockefeller's essay appears here as the foreword to this volume, which highlights the best and most striking objects in what is considered to be the single finest collection of Mexican folk art in the United States.
