And that brought back memories of old telephone dials, showing letters as well as numbers. All the early phones were black. The earliest light-colored phone I remember having was hanging on the wall in the kitchen of the first house we bought after I was married. My FB friend Tricia commented, "Yes. It was the 80s before we had a push button phone. And we had a party line when I was growing up!" Ah, yes, we also had a party line phone when I was a child.
A party line was a local telephone loop circuit that was shared by more than one subscriber. There was no privacy on a party line; if you were conversing with a friend, anyone on your party line could pick up their telephone and listen in.
