Original copy of "Hughes Helicopter 269 A Export Distribution Proposal Far East South America" from Air Carrier Service Corp., Report No 61-R54, Washington, D.C., April 24, 1961. The heavy paper pages have notes and underlining throughout the book, which seem to be edits. Very interesting. Please see the photos.
