This Paramount promo image shows U.S. actress Dorothy Lamour and, according to the rear, was made while she was boating on Lake Arrowhead taking a break from filming Masquerade in Mexico. That dates the shot as from 1945. By then she had already achieved great fame in several Road movies with Bob Hope and Bing Crosby, but some of her biggest box office hits were still in her future, particularly in 1947, when she made My Favorite Brunette, Wild Harvest, Road to Rio, fifth in the Road series. You can see another smiling Lamour here.
Your Honor, the deceased suddenly swam in front of me before I could react. I never took my eyes off the lake even a for second.
