In the run up to a bombing raid, it is common practice for mechanics or aviators to "sign" the bombs before they are loaded onto the plane. Their short messages - "with love", " best wishes"- are addressed to those about to be bombed.
This was the case with "Fat Boy", the bomb signed by American army engeneers days before the bombing of Nagasaki.
Best wishes is a series of period photographs taken before bomb attacks, showing the messages and their authors. Theses images are heightened with a 3D effect.
Generally used to make the photographed object "lead out" of the screen and seem closer to the spectator, here in 3D effect is reversed (blu on the left, red on the right). This reverse relief artificially creates depth within the photopgraph, so that the viewer finds themself in the position of the photographer when he took the photo.
