Licensing

[edit]
Public domain I, the copyright holder of this work, release this work into the public domain. This applies worldwide.
In some countries this may not be legally possible; if so:
I grant anyone the right to use this work for any purpose, without any conditions, unless such conditions are required by law.
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
This work is in the public domain both in Portugal and in the United States because it was first published in Portugal (and not published in the U.S. within 30 days) and it was first published before 1 March 1989 without complying with U.S. copyright formalities, such as copyright notice and it is one of the following:

  • A photographic work, work deemed to be a photographic work or work of applied art created before 1 July 1970 (more info here); or
  • Another type of work whose author died before 1946; or
  • An anonymous work or a work deemed to be anonymous, or a work by a collective person whose authors were not individually identified, published or disclosed before 1946.

For background information, see the explanations on Non-U.S. copyrights.
As of 1 January 1996, the following were in the public domain in Portugal: works whose author died before 1946; anonymous works, works deemed to be anonymous, or works by a collective person whose authors were not individually identified, first published or disclosed before 1946; photographic works, works deemed to be photographic works or works of applied art created before 1 July 1970; news articles or economic, political or religious articles, published or disclosed before 1996, provided that rights have not been specifically reserved and mentions, wherever possible, the name of the author and of the publisher, of the title of the work and other elements enabling it to be identified.

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.
