Thanks for the link. Great pictures. As far as copyright goes the page has this statement: The downloadable photographs from the Wartime Photograph Archive can be used by anyone. When you publish a photograph from the archive, mention "SA-kuva" as the source. You may not use the photographs to mislead people. You may not use the photographs for unlawful or inappropriate purposes.
I forgot to mention that there are over 3000 pictures on that website. From AA gunngers to Finnish troops on bikes. I am ignorant on this whole theater of the war. I think I'll be spending some money on Amazon tonight getting some new books. Does anyone have recommendations for me?
