I don’t remember the Jewel Tea Company, but the Watkins salesman Bill Porter used to sell door-to-door in our neighborhood when I was a kid. He was the guy with cerebral palsy that they made a movie about. Very nice person, though my sisters were scared of him because he walked and talked funny.
Never heard about Watkins. I was born and rained in Rochester, New York, and I only remember the Jewel Tea salesman coming to our house.
