Public domainPublic domainfalsefalse
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.
Reproducties van het werk kunnen ook worden beschouwd als publiek domein omdat ze geen oorspronkelijk karakter hebben. Dit geldt voor reproducties gemaakt in de Verenigde Staten (zie Bridgeman Art Library v. Corel Corp.), Duitsland en veel andere landen.
