A series of incredible images show how quickly the world can change. 

In photographer Patrick Strijards' "Old vs. New" collection, he combines images of Germany during World War II with photos of the present day. The photographs artfully contrast the broad sweeps of Nazi propaganda and the devastation of the war in Berlin with the vibrancy of the city today.
