In two volumes, this set was published in 1953 by the United Fruit Company, authors Richard B. Woodbury and Aubrey S. Trik. Both volumes are in black cloth hardcovers with gold lettering and map on front, two folded maps in rear pocket of volume I, with many other fold out maps, drawings, and photos and descriptions of entire exploration and restoration of Mayan ruins of Zaculeu. Vol I has pages 1-324, and Volume II has pages 325-466. In very good condition, with little apparent usage, with a slight scrape on the front edge of Vol I and a slight dent in the edge of Vol II, both visible in photo #3. Pages are slightly yellow, but could be the original tone of the pages. No slip case. An excellent reference set regarding this important Mayan ruin, with elaborate descriptions and images, this set is an important view into Pre-Columbian culture of the region.
