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. Users can compare the past and present of cities such as London, Paris, Washington and Saint Petersburg. This window to the past was created English entrepreneur David Webb, 45, the creator and CEO of the Timera app.
