Note that "photographic works", which must display artistic merit or originality, enter the public domain 70 years after the death of the photographer and that photographs that are not considered works but created 1 January 1970 or later become public domain 50 years after they were created. See Licensing for details.

Some countries have a lower threshold of originality and may therefore apply a longer protection term for this image, so it may not be usable in such countries.
