Lot-2292-6: WWII-Communications: Unusual Rear Scope Photoraph. An AAF photograph of an AAF bomber which came into the range of the radar beam of the airplane, from which this picture was made. It is unusual and would hardly be possible against an enemy airplane, in as much as it was made from a short distance away. U.S. Army Signal Corps Photograph: 29881 AC.
