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:
Any of the following acts are not considered Copyright infringement:
Publication, Distribution, Communication, and/or Reproduction of State emblems and national anthem in accordance with their original nature;
Any Publication, Distribution, Communication, and/or Reproduction executed by or on behalf of the government, unless stated to be protected by laws and regulations, a statement to such Works, or when Publication, Distribution, Communication, and/or Reproduction to such Works are made;
...
Reproduction, Publication, and/or Distribution of Portraits of the President, Vice President, former Presidents, former Vice Presidents, National Heroes, heads of State institutions, heads of ministries/nonministerial government agencies, and/or the heads of regions by taking into account the dignity and appropriateness in accordance with the provisions of laws and regulations.
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.
