File:Valtionarkisto 1957. Aslak Outakoski Hämeenlinnassa 20.-21.5. 1957 pidetyssä arkistokokouksessa. Kansallisarkisto.jpg

This file is from the official archives of the National Archives of Finland (Kansallisarkisto). The photograph is in the public domain in Finland, because either a period of 50 years has elapsed from the year of creation or the photograph was first published before 1966. The §49a of the Finnish copyright law of 2005 specifies that photographs not considered to be "works of art" become public domain 50 years after they were created. The 50 years from creation protection period came into force in 1991. Before that the protection period was 25 years from the year of first publication according to the §16 of the law of protection of photographs of 1961. Material already released to public domain according to the 1961 law remains in public domain, and therefore all photographs (but not photographic works of art) released before 1966 are in the public domain. See Commons:Copyright_rules_by_territory/Finland for details.

However, the National Archives asks that when material from its archives is used, the National Archives of Finland is cited as the source.
