To mark 70 years since the twin nuclear bombing of Hiroshima and Nagasaki in 1945, Harry Pearce from Pentagram created It’s All Our Blood, a poster made with his own blood. The video shows the process of making that poster, from doctor’s office to photography studio to printers. The result is as beautiful as haunting. The poster will be part of the exhibition Questioning the Bomb, which will open on September 2nd at the Gallery of Mainland.
