In the United States advertisements published in collective works (e.g. magazines and newspapers) are not covered by the copyright notice for the entire collective work. This advertisement lacks a copyright notice and was published before 1978 so it is in the public domain in the U.S.
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.
