Art: Mentalgassi Fence Designs

In attempts to raise awareness about Troy Davis, a man who has spent 19 years on death row in the US despite doubts about his conviction, renowned graffiti artist Mentalgassi has teamed up with Amnesty International to do a "Making The Invisible Visible" street art project in which he places portraits of Mr. Davis on various fences throughout London.

Mentalgassi is a German street art collective who uses prints and wheatpaste to transform urban objects into works of art. His slogan is to "create street art to open your eyes." Enjoy the rest of Mentalgassi's amazing Fence Flip Graffiti photos below!
