Hi,
Is anyone here familiar with the book ABOUT FACE by David Jury? See below

I really wanted to find out exactly the main typefaces used throughout this book.
And also the vendor I could purchase these typefaces from.
Also I am after an entire family of Helvitica in its purist form, as in closest digital version
to the original and best family. I have “bit and pieces” of helvetica laying around but nothing
in its entirety (family etc).
I hope I made sense here. Any help would be much appreciated.
