French art director Julien Knez spent a summer taking photos of Parisian streets overlaid with vintage photos of what they used to look like.
The vintage photos range from 1871 to 1968, and highlight key moments in Parisian history, from the great flood of 1910 to the city's Nazi occupation and liberation.
Knez turned his project into a book, Paris, Fenêtres Sur l'Histoire, published by Parigramme, which contains 80 images of modern Parisian streets overlaid with old photographs that reveal what the French capital looked like over 100 years ago.
