Award First Printing Cover Scan.
Five desperate people schemed to steal it:
- Hermann Goering, Reichsmarschall.
- Max Rader, Hitler's personal aide.
- Shikoku Hondo, Colonel of Japanese Intelligence.
- Baroness Elspeth von Stadt, Voluptuous double agent.
- Nick Carter, AXE agent.
Award Books updated this title in 1973 to be written in 1st person. There were lots of errors and it was the only title to be written in third and first person. First person point of view became stand for the series in 1969. There might be a fourth printing with book number A315 out there as I do not have that one. Awards reprinted a lot of titles in 1970 with the same book numbers while reissuing a few new book numbers.
Here are the cover scans from the second (A152F, August 1966) and third (A315X, 1969) printings.
