No wide-angle lens is wide enough to capture the entire length of this massive more than 100 meter long collaboration piece by Blu and Ericailcane at Lambrate train station in Milan.
The mural is quite faded now, two years after it was made. But have a look at pictures from when it was fresh at Blu's web page here and Ericailcanes web page here. Thanks to Walls of Milano for pointing out the spot. Check out Walls of Milano's wideangle photos:
