John, that picture is of both Mrs. Wilsons on Dennis the Menace. The lady on the right is Sylvia Field. And I know I'm being picky, but it's Sara Seegar, with an "a" near the end. Her last name sort of sounds like the way we pronounce cigar in the South. A cee-gar.

Sara Seegar was also one of the River City ladies in The Music Man. One of my favorite movies. Ronny Howard was also in that movie.
And about the Hooterville Sarah, played by Merie Earle, I loved what she did when she had to leave the switchboard. She had a Victrola with a morning glory horn atop the switchboard and she'd play a recording saying she was home basting her rump roast or some such thing. Hank Kimball said at one time they sold copies of the record as Sarah's Greatest Hits. You gotta love the writing on that show.
