June Allyson and Dick Powell, Hollywood icons who married in 1945 (with Louis B. Mayer  giving away his MGM star), hold hands as they ride around with their daughter, Pamela Allyson Powell, in the rear. It’s 1957, when Powell directed the Robert Mitchum/Curt Jurgens war movie The Enemy Below and Allyson starred (opposite David Niven) in a remake of My Man Godfrey. Photo: Dick Miller, for Globe Photos.
