To judge from the 1971 date, the text was most likely set on an IBM Selectric Composer using one of that machine's proprietary faces, probably Press Roman. I can't identify the sans-serif font in headline, but I think it's dry transfer lettering. The largest size on the IBM Selectric Composer was 12 point, and transfer lettering was a popular low-budget solution for display type in the 70s.

THANX!
What digitalized font would you suggest I use to imitate Press Roman?

You might get a similar feel to this sample with ITC Bookman.

I used the Serif Font ID Guide and found that Gazette or Imperial may be closer matches than Bookman. Both were designed by Ed Shaar in the 1950's, so would have been available as metal type.

I don't think this book looks like it was done with a typewriter, because some rather awkward spacing was used to justify the margins. I don't think a typewriter would be able to do this.

Sorry, I see Mojo was talking about an IBM composer, not a typewriter, and that might be right. I am not familiar with that equipment, but I do think digital versions of Gazette or Imperial might look closer to the type than Bookman.

Mike, Gazette looks like a winner. The IBM Composer could justify lines, though as the sample shows, its justification capabilities were limited.
