A very interesting photographic collection. No page numbers. 2nd Edition published Mexico D.F. 1946. First Edition published 1933 was sold out and the National Institute of Anthropology and History decided to publish this updated edition. Descriptions in English and Spanish. Condition is good except that light board cover is detached from bind 200mm down from the top edge but this does not affect the overall appearance. Otherwise the binding is tight except for strain between plates 12/13 and plates 14/15. Photos are all clean and undamaged.
