National Brothers and Sisters. London teamed up with the anonymous German street art collective, Mentalgassi, to create art installations for Amnesty International. They 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. Troy Davis: Making the invisible visible from Amnesty International on Vimeo.
