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.
The author died in 1941, so this work is in the public domain in its country of origin and other countries and areas where the copyright term is the author's life plus 80 years or fewer.
You must also include a United States public domain tag to indicate why this work is in the public domain in the United States.
Note that a few countries have copyright terms longer than 80 years: Mexico has 100 years and Jamaica has 95 years. This image may not be in the public domain in these countries, which moreover do not implement the rule of the shorter term.
