This work is in the public domain in the United States because it was published (or registered with the U.S. Copyright Office) before January 1, 1929.

This UK artistic or literary work, of which the author is unknown and cannot be ascertained by reasonable enquiry, is in the public domain because it is one of the following:

• A photograph, which has never previously been made available to the public (e.g. by publication or display at an exhibition) and which was taken more than 70 years ago (before 1 January 1954); or

• A photograph, which was made available to the public (e.g. by publication or display at an exhibition) more than 70 years ago (before 1 January 1954); or

• An artistic work other than a photograph (e.g. a painting), or a literary work, which was made available to the public (e.g. by publication or display at an exhibition) more than 70 years ago (before 1 January 1954).

This tag can be used only when the author cannot be ascertained by reasonable enquiry. If you wish to rely on it, please specify in the image description the research you have carried out to find who the author was. The above is all subject to any overriding publication right which may exist. In practice, publication right will often override the first of the bullet points listed.

Unpublished anonymous paintings remain in copyright until at least 1 January 2040. This tag does not apply to engravings or musical works. More information

The copyright situation of this work is theoretically uncertain, because in the country of origin copyright lasts 70 years after the death of the author, and the date of the author's death is unknown. However, the date of creation of the work was over 120 years ago, and it is thus a reasonable assumption that the copyright has expired (see here for the community discussion). Do not use this template if the date of death of the author is known.

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 70 years: Mexico has 100 years, Jamaica has 95 years, Colombia has 80 years, and Guatemala and Samoa have 75 years. This image may not be in the public domain in these countries, which moreover do not implement the rule of the shorter term. Honduras has a general copyright term of 75 years, but it does implement the rule of the shorter term. Copyright may extend on works created by French who died for France in World War II (more information), Russians who served in the Eastern Front of World War II (known as the Great Patriotic War in Russia) and posthumously rehabilitated victims of Soviet repressions (more information).
