Both my mother and I had that type of passport when I was a little kid. Must have been early 70s, I'll check the dates. However, they were issued to us because we were heading to the UK to be with my dad who went ahead of us to set up house. He was US Air Force and there's an endorsement stamp inside each declaring them to be "Official Business" passports.
