The Dutch historian Jo Hedwig Teeuwisse found 300 old negatives at a flea market, many depicting scenes from World War II. She researched the locations, took photographs from the same spot, and overlaid the two. The results are haunting. You can see the original two photographs below. And if this reminds you of Historypin, then you are a winner!
