These time-slip pictures combine recent photos digitally stitched together with historic photos from World War Two, or as it was known in Russia, 'The Great Patriotic War'. During WWII the Soviet Union suffered nearly 25 million casualties.
These pictures show current day views of Berlin, Leningrad and other WWII sites with images from the war bleeding through like ghostly reminders of the not to distant past. They are in some ways a visual analog to the time-slippage experienced by Kurt Vonnegut's character Billy Pilgrim in Slaughterhouse 5. Kudos to Sergey Larenkov for these images.
The pictures I have chosen here are only a sample from the Leningrad images:
