Thank you to the eagle-eyed reader who sent in the previous Colombo "Rudy-Bomb". Yesterday they sent one more (see below) They wrote:
"I discovered another Rudy photobomb. I was watching the film, Cheaper by the Dozen, with Clifton Webb and Myrna Loy. In this scene, they are in their daughters' bedroom. And who should appear on the wall? And then it hit me how both Webb and Loy have connections to Valentino. Rudy took Webb's place dancing with Bonnie Glass. Loy was discovered by Rambova and had a part in What Price Beauty. It's funny I have seen this movie a few times before and never notice the photo of Rudy in the background."
