In quest of a movie frame

Because of a project of mine, I’m looking for a movie frame, if the one I’m looking for exists!
The qualifications are:
Black&white movie, much better if it’s old, public domain
in which a scene is setted into a theatre, with the public who stand up for leaving at the end of a screening and the writing “the end”, or the end credits, appearing. “The end” can appear on the screen of the theatre or can signal the real end of the movie I’m looking for, it doesn’t have importance. The lights on the theatre can also be on and there can be nothing more on the screen, it’s ok too.
The image I’m looking for can also be a real black&white photo, taken on a real theatre at the end of a screening, published on an old magazine.
