Note that it may still be copyrighted in jurisdictions that do not apply the rule of the shorter term for US works (depending on the date of the author's death), such as Canada (70 years p.m.a.), Mainland China (50 years p.m.a., not Hong Kong or Macao), Germany (70 years p.m.a.), Mexico (100 years p.m.a.), Switzerland (70 years p.m.a.), and other countries with individual treaties.
Even if the yearbook bears a copyright notice, no copyright renewal was found in the Stanford Copyright Renewal Database for any edition of the X-ray, or for any work by St. Xavier High School, for that matter. (As an annual publication, the X-ray would have fallen under Class A.)
