The History of Fort Vancouver and its Physical Structure. Limited and numbered. This is #277. 
No date given, but the book was printed prior to 1957. No dustjacket as issued. 

Very good condition overall. You'll see some light, general wear near the top and bottom of the spine and a small, slightly crunched in area on the upper left of the cover, but it's pretty minor. On the inside, the pages are clean, and the binding is strong for the vast majority of the book, though it is noticeably strained in the back sections with the maps and photos. One of the edges of the maps has also been folded/ a little crumpled. (See pictures.) 

Please let me know if you have any questions and thanks for looking!
