Public domain
This Swedish photograph is in the public domain in Sweden because one of the following applies:
  • The photograph does not reach the Swedish threshold of originality (common for snapshots and journalistic photos) and was created before 1 January 1974 (SFS 1960:729, § 49a).
  • The photograph was published anonymously before 1 January 1954 and the author did not reveal their identity during the following 70 years (SFS 1960:729, § 44).

For photos in the first category created before 1969, also {{PD-1996}} usually applies. For photos in the second category published before 1929, also {{PD-US-expired}} usually applies.

If the photographer died before 1954, {{PD-old-70}} should be used instead of this tag. If the author died before 1926, also {{PD-1996}} usually applies.

You must also include a United States public domain tag to indicate why this work is in the public domain in the United States.
