As we posted previously, MyHeritage.com is going to be attending this Saturday's family history event at the Imperial War Museum, London.
Since this event is focusing on World War II and the Blitz, we thought we'd share with you some fantastic images from that time. These are photos of London during the Blitz, but not as you know them. They've been superimposed on modern images from Google street view.
If you like these, stay tuned for tomorrow, when we'll let you know how you can generate images such as these for yourself - and for places and times beyond WWII London.
As always, just click on any of these images to enlarge for a better view.
