Codes Ciphers and Secret Writing 

Martin Gardner

Pocket Books, NY. 1972. Paperback. Very good copy with just slight edge wear to cover and some yellowing to the rear cover.

From the publisher:

"Learn to use the most important codes and methods of secret communication in use since ancient times. Cipher and decipher codes used by spies. Explore the famous codes that changed the fate of nations and political leaders. And enjoy hours of fun experimenting with cryptography ― the science of secret writing. "

A fun workbook and history of code and ciphers. Recommended to steel your mind against impending algorithmic domination.
