Orhun Türker, an artist from Turkey, has been working with the intography technique. This one is his third project and his earlier work appeared in magazines including but not limited to Photoline and 362 life.
For those who don't know: intography is a collage technique including putting together old photos of cities and scenes with the new photos shot at the same angle.
The photos you will see were taken Bolu, a city in northwestern Turkey, and according to Wikipedia, "it's an important midpoint between the capital, Ankara and the largest city in the country, Istanbul. It covers an area of 7,410 km², and the population is 271,208."
