Elizabeth Montgomery was a movie and tv actress whose career began in the 1950s. She guested on many tv shows until she landed the starring role as 'Samantha Stephens' on the 1960s sitcom "Bewitched". Of all the various roles she played in other tv shows and movies over her long career, it's this one for which she will always be remembered.
In 1983, I sent her this photo, to her home address in Beverly Hills, California, and she returned it within a month.
Here is a "Bewitched" mini episode.
