Published in 1954 by Princeton University Press, compiled by Harry W. West, Maps executed by H. Lester Cooke, Jr., and J. McA. Smiley.  This is Volume 1w of Princeton Oriental Studies Philip K. Hitti, General Editor.  This particular copy is the Third Edition, Revised and Corrected, in 1954.  It has a copyright date of 1951, so I assume that was the year of the First Edition.  Thick front cover with soiling and a moisture stain bottom edge mostly near the fore edge. The back cover has a more prominent moisture stain top edge that extends a bit on the last few pages.  There are 49 pages with the 49th page the back of the back cover.  There are 20 maps - ALL COULD BE FRAMED.  There are no moisture stains on the maps, but there are small foxing marks at the bottom of pages seen on the first several maps.  See listing photos for examples.
