Looking for a specialty art poster

This poster was at the Hollywood Eqyptian theater in the front glass west window and is a pic of Bob Hope, Vera Miles and an accordian player. The musician is my dad. The poster went on to the next theater with the film and has never been seen since. This image is not in the press book and is not in any of the lobby cards in the set. The musician is wearing a policeman's uniform and a police cap, something like from one of the boroughs of New York. I'm not a collector, would love even a copy of that poster. The musical director Lilly is deceased as is the photographer from the film. Bob Hope's secretary had never seen that poster. Hope to find it soon. thanks!
