DescriptionMutual Black Network 1974 Commercial Poster.jpg
English: Low-resolution reproduction of newspaper advertisement for the Mutual Broadcasting System's Mutual Black Network, featuring Dr. Martin Luther King Jr. and Nikki Giovanni, 1974
The image was published as an advertisement in the U.S. in 1974. There is no evidence that copyright notice was originally filed on the image, as then required. For instance, this image evidently shows the entire advertisement and no copyright notice.
There is no evidence that CBS Corporation, the corporate heir to Mutual Broadcasting System, or American Urban Radio Networks, the corporate heir to Mutual Black Network, claims copyright on the image.
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.
