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 on both the front and rear covers. The single "classes" page that appears before the student photos is loose,, but it is in good condition. All other pages are fully bounded. There are some signatures and 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.
