Prisms and Shamrocks

The Spring 2015 Brain Washing from Phone Towers Informational Pamphlet concerns the history of cryptography, and asks the following questions: How do we solve the problem of communication at a distance? What is the best way to communicate secrets? Has the government always been reading our messages? What kinds of things do we substitute in place of language in order to keep things private? And other related issues, in easily portable paper form. I promise no one will eavesdrop on you while you read it. Printed letterpress from handset metal type and linoleum blocks in an edition of 200.
