The original document looks like it was printed on typing paper by some guy in a Quonset hut. It consists of 101 "figures," beginning with a diagram, followed by post-strike maps of Hiroshima and Nagasaki, followed by 98 captioned photographs. Quality of photographs varies from good to terrible. The maps have very high resolution, and are interesting to inspect closely. If you are looking for an iconic image, see figure 72.
