Mentalgassi for Amnesty International

"Brothers and Sisters creative team Lisa Jelliffe and Kirsten Rutherford have teamed up with the anonymous German street art collective Mentalgassi, to create art installations for Amnesty International.
We've called the installations 'Making the invisible visible'. They highlight the case of Troy Davis, a man who has been on death row for 19 years in the USA, despite serious doubts about his conviction. The posters are displayed on fence railings. Front on, you see nothing but bars. Troy's face only becomes visible from an angle. Please help save Troy from being executed."
