Miss Swanson made two appearances as a mystery guest on What's My Line, first in the first season of the show, in 1950. LOVE that hat. She appears at 15:22, and has a little trouble getting offstage, dear girl.

She appeared again in 1965, on the show in which they celebrated their 15th anniversary. Love her hair, and that darling little dress (is it a Dior, or a Balenciaga, or similar?). She appears at 4:38.
