This is the 1931 Zonian yearbook from Balboa High School, located in the town of Balboa on the Pacific side of the former Canal Zone on the isthmus of Panama. This yearbook is in used condition with a weak binding and partial separation of the rear cover and advertisement section. One of the advertisement pages is loose,, but it is in good condition. There is insect damage at the bottom of all pages, but none of this damage eliminates any information on the pages. There are signatures and a few stains on some of the pages, but overall, everything is very readable and in decent condition for such an old yearbook. Please view the photos below to see the condition of representative pages. The advertisements are really great and are one of the highlights of this yearbook. They bring back memories of what life was like on the Pacific side of the former Panama Canal Zone.
