Graphic Standards System
Designed by Steff Geissbühler,
Chermayeff & Geismar Associates
The EPA Graphic Standards System is one of the finest examples of a standards manual ever created. The modular and flexible system devised raised the standard for public design in the United States.
The book features a foreword by Tom Geismar, introduction by Steff Geissbühler, an essay by Christopher Bonanos, scans of the original manual (from Geissbühler’s personal copy), and 48 pages of photographs from the EPA-commissioned Documerica project (1970–1977).»
