Now this isn't a new idea, but I still think it's clever- "Taking old World War II photos, Russian photographer Sergey Larenkov carefully photoshops them over more recent shots to make the past come alive. Not only do we get to experience places like Berlin, Prague, and Vienna in ways we could have never imagined, more importantly, we are able to appreciate our shared history in a whole new and unbelievably meaningful way."

I thought the photos were a neat when I first saw them on the English Russia website English Russia » Leningrad Siege: Now and Then English Russia » St. Petersburg: Now and Then 2 I think this is all of them in one shot Leningrad 1940, St. Petersburg 2010 | archipaedia.net
