OFFERING a glimpse into the past, a mash-up of old and new photographs show how the world’s biggest cities have changed. A new phone app allows users to travel back in time by overlaying vintage images, such as London's Tower Bridge in 1892 or the Eiffel Tower in 1940, with how the locations look today.
