This interesting work of art is actually old photos superimposed on present day scenes. It shows how it was back in the days and how it is now. The brains behind the project are several photographers from a flickr group who have managed to cooperate and create an amusing art piece by only using photography as the main tool. There are some very cool transformations and you will be surprised how different it looked before. A transformation that is especially fun to check out is the one on Dubai. If you want to do the same as these members of the group did, you need lots of time, a bunch of old photographs of buildings, structures and locations, a photo camera, and last but not least creativity. It can make an interesting hobby.
The flickr group contains several hundreds of photos, but here are the best 25. Something that can remind of this project is these amazing drawings combined with photography.
