.... and be enlightened.
This book is one of the "classics" of the conspiracy genre, and has become something of an historical item in its own right. It was originally distributed as part of the 1972 presidential campaign of the "America Party", whose candidate, Rep. John G. Schmitz, wrote the introduction. Both Schmitz and author Gary Allen were closely tied to the John Birch Society, and there is a plug for the JBS at the end of the book.
Thanks for the laugh.
