French artist JR has just completed a new installment of his “Wrinkles of the City” project in Istanbul. He first began the series (covered here) in 2008, as an effort to paint a portrait of urbanization around the world. Istanbul, the largest city in Turkey, is the economic and cultural center of the country. With a population of 14.4 million people, it is also the largest urban agglomeration in Europe – more than 60% of people living there were born out of the city. As an answer to the growing lack of space, buildings are being demolished to make room for the construction of new neighborhoods. JR spent two weeks on top of its roofs and in its streets, installing large scale images of its elder generation, who have shaped and been affected by Istanbul’s population shift. Now their faces, wrinkles and all, become a part of it as well. Take a look at more images of JR’s “Wrinkles of the City” in Istanbul below, courtesy of the artist.

In recent years, Mexico City has played host to some of the most progressive urban artists in the world. Many of them have come together in Celeya Brothers' anniversary exhibition, "Cuatro Igual A Uno": 3TTMan, Christiaan Conradie, Franco Fasoli aka JAZ, Fusca, Augustine Kofie, Lesuperdemon, Sten & Lex, Sanez, Smithe and Jorge Tellaeche. The group represents not only the freshman artists to show with the gallery, but also the city's international draw, hailing from the United States, South Africa, to Argentina. Take a look at more photos from the exhibition after the jump.
