The high school yearbook has no copyright markings on it, therefore it lapsed into public domain.. Also, colorization was done using MyHeritage in Color™. If you think colorization is not appropriate, please feel free to make it black and white.
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 (50 p.m.a.), Mainland China (50 p.m.a., not Hong Kong or Macao), Germany (70 p.m.a.), Mexico (100 p.m.a.), Switzerland (70 p.m.a.), and other countries with individual treaties.
