Billboard made "transparent"

Artist Cayetano Ferrer photographed the trees hidden by a 30-foot wide billboard in Daejeon, Korea and then pasted the image on the billboard. He purposely left part of the billboard white and put that missing piece of the image on another smaller billboard nearby. Link

Previously on BB:
• Cayetano Ferrer's "erased" products displayed on city street Link
• Transparent street signs Link

UPDATE: Here is a Chief Magazine interview with Kasia Kesicka, another artist who turns billboards transparent. Link
