This piece of art has popped up from time to time over the decades (it dates from 1959 or before), showing a schematic view of the basic layout of a nuclear-powered bomber. And while the version below is not particularly clear or high-rez, it has the advantage of being in color.
The truly gigantic-looking bomb is likely not pure artistic license. At the time Lockheed was designing bombs that looked just like this at extraordinary size; they had substantial rocket propulsion capability to let the bomber release the weapon at a considerable standoff distance.
