New York City MTA Graphic Standards Manual ⇥ blog.fawny.org

Joe Clark:

I’ve been trying to get my hands on a copy of the New York City Metropolitan Transit Authority Graphic Standards Manual ever since Triborough managed to do so. This style manual, written by Massimo Vignelli and Bob Noorda for Unimark, is the sword in the stone of transit wayfinding manuals.

The absolute exquisite standard for transit signage. Via John Gruber and, since he linked it, the 94 MB PDF download is a bit slow (but, oh my, is it worth the wait).
