I have to approve all comments, so if your guess is posted immediately, that means you're wrong. (And if a wrong guess has already been submitted by someone else, there's no point in submitting it again).
If you're right, you will have to wait until Friday. There's no need to submit your guess five times. Once is enough. The only reward is bragging rights.

Update: The caption information on the back of the photo, stamped Oct. 15, 1950, says, “Unimpressed by the celebrated glamour of his opponent, many Hollywood celebrities are working energetically to elect Rep. Richard Nixon to the United States Senate. Here are a trio who have teamed up to work in the Nixon-for-Senator campaign: Irene Dunne, Louise Beavers and Hedda Hopper.”
Wow! Nearly everybody identified our mystery guest, too many folks to list everybody’s name. Here’s another picture of our mystery guest with two (not very) mysterious companions. Aren't the hats great?

Update: Louise Beavers and Postmaster Mary D. Briggs in an undated photo.
Daily Mirror readers are certainly sharp! Everybody recognized yesterday’s (not very) mysterious companions. Today’s mystery companion may be a little more difficult.

Update: Louise Beavers, Ann Sheridan and an unidentified actor (suggestions include Clinton Sundberg and Dick Ross) in “Good Sam,” Sept. 15, 1948.
And here’s our mystery guest with two more mysterious companions. So far nobody has identified yesterday’s mystery companion – but she’s tough.

Harkening back to those days when African-Americans on American screens were sadly relegated to subservient roles, Louise Beavers played ‘Beulah ‘ on TV.
Actors had to work. But so much great talent was wasted.

It’s that wonderful character actress, Louise Beavers. She makes Cary Grant’s day in, Mr. Blandings Builds His Dream House, by coming up with the advertising line, ” If you ain’t eatin’ Wham, you ain’t eatin’ ham!’
