New York: Aperture, 1993. Later printing. Hardcover. 399 pages. A powerful collection of black and white photographs of people at work throughout the world. A clean and tight near fine copy in a close to near fine dust jacket that is lightly rubbed and with some minor wear and some scratches to the rear panel. Includes the booklet in the rear pocket. Still a nice copy of one of Salgado's best books.
