Of the people named or implied to be named, the last, the son John Annan, died in 1947:


This image is in the public domain because it is a mere mechanical scan or photocopy of a public domain original, or – from the available evidence – is so similar to such a scan or photocopy that no copyright protection can be expected to arise. The original itself is in the public domain for the following reason:
Public domain

呢個作品嘅作者喺1947年過身，喺來源國同埋其他版權期限係作者過身後75年或以下嘅國家同地區屬於公有領域。

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 file has been identified as being free of known restrictions under copyright law, including all related and neighboring rights.

This tag is designed for use where there may be a need to assert that any enhancements (eg brightness, contrast, colour-matching, sharpening) are in themselves insufficiently creative to generate a new copyright. It can be used where it is unknown whether any enhancements have been made, as well as when the enhancements are clear but insufficient. For known raw unenhanced scans you can use an appropriate {{PD-old}} tag instead. For usage, see Commons:When to use the PD-scan tag.

Note: This tag applies to scans and photocopies only. For photographs of public domain originals taken from afar, {{PD-Art}} may be applicable. See Commons:When to use the PD-Art tag.

Or, if we presume the photographer is anonymous, it's still published before 1929, the year that things automatically go out of copyright in the United States, so that's fine, and it's also still out of copyright in the UK under:

Public domain logo
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).

Warning sign 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

  1. ↑ File:Baron-Kelvin-William-Thomson-compass-1902.jpg identifies the photographer as specifically James Craig Annan, but I can't find any source for that attribution.

Additionally, the National Galleries of Scotland offer a CC-by-NC license, for which they suggest Wikipedia as a suitable use. Nice of them, and I'll take advantage of their offer, but to upload, have to claim {{PD-Art}} or {{PD-scan}}
