What to read after Public Address System?

"This book features a collection of posters by typographers that were featured in an exhibition of the same name in London and Berlin. The brief was simple: to design an A2 poster that was a typographic interpretation of a speech." "The typographers' responses to the project brief are awe-inspiring and provoke deep thought about not only the issues addressed by the often-famous speeches, but also about the very nature of speech, typography and posters. The featured works are made from all manner of materials, from Perspex, to gold foil, to a collage, including torn book pages and even a 7-inch vinyl records."--BOOK JACKET.
