My goal is to honor him and make a game similar to Command & Conquer and incorporate the character of Simo Häyhä in the game. However I'm going about this the DIY way building my own game engine. Those interested can find more info here:
Lots of WWII-era aircraft, vehicles, naval assets, etc in color.
There are many events documented with multiple slides that are out of order but these photos appear to all have dates assigned and references to locations so it should be possible to identify what was happening.
Someone could assemble this collection in chronological order and it would likely tell a coherent story of the war as it affected Finland.
There are also war-time videos and the entire collection according to the site contains more than 160k photos. They were taken by units tasked with documenting the war and its effects.
This is a huge resource with a lot to see.
Edit: Nvm, was some ruins on page 3 at least.
But yes the pictures are certainly fine and useful for historians.
