signage, Vignelli map

I saw a potion of the Vignelli map in the Times a couple weeks ago when the
new map was announced. Can one still get a copy of the map full size? What
little I could read of it in the article photo made much more sense to me
than any other I have tried to use (not that I need it for navagation, but
it is a much more arresting image then the behemoth recently released)
