Regarding this old thread:

I wonder if soemone could elucidate? The consensus seems to be that Glaser used American Typewriter Bold - a "no-brainer." But the version on Milton Glaser's web site:

as well as every version I have ever seen, is slightly different. ITC American Typewriter has a lot more color than Glaser's version.

Any ideas?
