Between the BANTAM editions and the All-New WILD ADVENTURES, there were fans, some of them even professional authors, who could not find a place to share their Doc Savage adventures.  A nameless someone organized some of the best and had them privately printed.  From what I have been able to find out, there are only 100 to 200 copies of each book.  This one reads like so many of the classic novels.  I thoroughly enjoyed it.
