Second, I suspect the photo you posted was taken from a magazine. That's how most people experience commercial photos. The offset printing process matters a lot too. Not before the 80s were CMYK separations routinely made via laser scanning. Finding someone today who can/wants to do analog CMYK is next to impossible, so your best bet would be to simulate the result.
Agreed. Too often faded, shifted 60s-70s print media are seen as a "look" to shoot for now. The style of these shots is one thing, but deteriorated ink/paper just isn't that attractive.
I've been looking at old Sam Haskins stuff recently from the 60s and 70s, especially his b&w work, for project lighting clues. Jonathan Leder's Jacques magazine is a retro "gents" magazine shot only on film with interesting results:
