Komentář k Licence:

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 1973 (SFS 1960:729, § 49a).
• The photograph was published anonymously before 1 January 1953 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 1928, also {{PD-US-expired}} usually applies.

If the photographer died before 1953, {{PD-old-70}} should be used instead of this tag. If the author died before 1926, also {{PD-1996}} usually applies.
