DescriptionBring 'Em Back Alive (1932) film premiere.jpg
English: New York premiere of Bring 'Em Back Alive (1932), which occurred prior to the film's general release. This image is from Frank Buck's autobiography All In A Lifetime (1941), which is now public domain. The copyright was never renewed because the publisher, Robert M. McBride, declared bankruptcy in 1948, and the book went out of print.
This work is in the public domain because it was published in the United States between 1929 and 1963, and although there may or may not have been a copyright notice, the copyright was not renewed. For further explanation, see Commons:Hirtle chart and the copyright renewal logs. 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.
