Federal Irrigation Projects, Bureau of Reclamation. The Sesquicentennial International Exposition, Philadelphia Pennsylvania U.S.A., June 1 to December 1 1926
Washington DC: GPO / U.S. Department of the Interior, 1926. Pamphlet. ii, 50p., illustrated in b&w photography fuzzily reproduced, generally a photo on every page starting from p.10. Softbound, 9x6 inch pamphlet staple-fastened. A GPO item with both covers printed in colors, rather unusual, perhaps a boost for this little-known Exposition. Item has suffered damp-damage, to covers, not to text pages, staining not particularly severe however obvious. The staples, exposed where these protrude at the centerfold map, are slightly rusted with negligible migration. In sum, a fair to "good-only" copy.
Captions demonstrate that the sole concern here is for western states, Montana to California, southwestern from New Mexico.
