Black rotary, like most of the others..we had a party line for a while, then my mother went to a limited line, after my 1/2 sister got to be a teen.....gee, can't imagine why <grin>
When we lived a short time in Michigan, we had a wall-mounted crank [generator] phone. I never used it, but my mother or father would pick it up, and often times just ask for the person they wanted by name...the operator knew everyone . But they would sometimes ask for a 4 digit number. Maybe a temp was working...?
