I certainly would have thought this 'book' could encompass the Great Depression (1929 and on). It is the most defined 'doomsday' we should all learn from and act upon. I bet it is hard for anyone to learn from a distant past. Then I understood it was very law centric and that nothing was made to prevent a blackout, but mainly to escape any legal process that could interfere with any crisis management.

But my main focus was on the use of the Comic Sans font on page 1.
