Portuguese born street artist Vhils has an original vision of what urban development really means, and he travels the globe exposing what's beneath the surface of city walls .
Using various tools to dig, drill, scrape and otherwise remove sections of masonry, he reveals the images hidden behind the smooth walls, and the results are nothing less than spectacular. He should call his style of art urban erosion sculpture!
"This excavation, often a process of violent removal, stands in sharp contrast to the delicate portraits discovered hidden underneath."
Can you dig it?
