Unbeknownst to me the woman standing with Agnes in this picture is none other than the baby sister of Rosalind Russell. Her name is Elizabeth Roberta Russell and her nickname is Lee. She gave testimony on behalf on Agnes testifying to abuse witnessed at the hands of Jack Lee during the divorce trial....small, small world!
Found a snap of this with slightly different point of view in the L.A. Times May 1951 that identifies Elizabeth Russell as a witness on behalf of Agnes.
