Various sweet water fish with Finnish text, from a 1925-1928 encyclopedia, "Pieni Tietosanakirja", now in the public domain. Scanned in 300 dpi by Lars Aronsson, 2005. Also available at http://runeberg.org/pieni/2/0143.html (which explains the somewhat cryptic filename).

This image is in the public domain because the Finnish Copyright law of 2005 specifies that all "works of art" become public domain 70 years after the death of the creator, or 70 years after the date of publication if the works are anonymous. (Note: Photographs which are not considered to be works of art become Public Domain 50 years after their creation (§49, a)). See Licensing for details.
