Interesting photo of the young gang (minus Noodles) with the ice truck I'd never seen before. Posted on Facebook today. The truck appears twice in the movie. If my memory serves correctly, once in a photograph hanging in Fat Mo's back room, significantly next to a photo of Deborah, a "big star now", and once trundling up the street during the watch theft.
I am virtually certain that's Leone holding the camera, not Tonino Delli Colli
