This work is in the public domain because it was published in the United States between 1929 and 1977, inclusive, with a defective copyright notice (copyright notice information) containing at least one of the following defects:
Notice is dated more than one year later than the actual date of first publication;
Notice does not include a named claimant or does not name the actual copyright holder;
Notice is illegible or concealed from view;
It is a printed literary, musical, or dramatic work that does not include the year.
A defective notice does not invalidate copyright in cases where the error is immaterial and would not mislead an infringer, such as an abbreviated name. Additionally, foreign works created outside the US are subject to copyright restoration even with a defective notice. It is not in the public domain in the countries or areas that do not apply the rule of the shorter term for US works, such as Canada, mainland China (not Hong Kong or Macao), Germany, Mexico, Switzerland, and other countries with individual treaties.
The author died in 1929, 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.
