PLEASE NOTE, although I cannot verify the New York Daily News masthead one way or the other (I cannot access it), there is no copyright claim or notice on the newspaper masthead of the May 14 1969 Times Standard edition, in which this image is published on the front page.
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.
