10 artists, a pair of photgraphers, and a writer all got together to create and document beauty in Paris’ underground tunnels recently. Similar to The Underbelly project that took place in the abandoned train tunnels under New York City, the latest Underbelly secret spray session is seeing the light of day in newly released pictures. Check out some of the photos of this amazing art project since you will probably never get to see these works in person.
