Making the Invisible Visible is an Amnesty International street art project highlighting the plight of six individuals from the 2011 Letter Writing Marathon. The project is a unique collaboration between German street art collective Mentalgassi and creative team Lisa Jelliffe and Kirsten Rutherford from Wieden + Kennedy London. The installations use special lenticular fence posters. Launched in London in 2010 to highlight the case of Troy Davis, this year the campaign can be seen in 26 locations across 6 European cities. Each installation depicts a close up of an individual’s face. The image is invisible from front on, only becoming visible to those approaching the fence. A plaque on each site alerts passers-by to an Amnesty International website where they can take action in support of each of the individuals featured.
