Troy Davis was convicted of the murder in 1991 in Savannah, Georgia, USA, and despite doubts concerning his conviction, has been on death row for the last 19 years.

Since 2007, Amnesty International has been campaigning for a new trial. Finally in August of 2009 the US Supreme Court granted Troy another chance to prove his innocence in the form of an evidentiary hearing.

As a means of bringing attention to the case of Troy Davis, anonymous German Street art collective Mentalgassi and UK-based brothers and sisters have developed lenticular fence poster installations across London for Amnesty International.

The poster project entitled ‘making the invisible visible’ depicts the face of Troy Davis painted on fence railings.
