From the recently-released newsreel site: here’s one covering Madame Chiang Kai-Shek’s much publicized wartime speech at the Hollywood Bowl in April 1943.
At 0:06, you’ll catch a brief view of numerous Hollywood actresses who were guests of honor at the event, including in the shot here Norma Shearer, Irene Dunne, Ida Lupino, Mary Pickford, Loretta Young, Ginger Rogers, Rita Hayworth, and I believe that’s Shirley Temple’s hair behind Pickford.
Here’s a screenshot from the newsreel (left), next to a well-known photograph that is often, mistakenly, attributed to be from an Easter celebration.
