Does Anyone Know...

…the source of the black & white film clips shown briefly in the movie? They clearly are from the late 60's or early 70's, and there's one scene in particular where Valentino enters a room, folds his arms and leans against a doorway while several models turn and look at him. What was that? It almost looks like a scene from a old movie, but there's nothing listed in his film appearances that corresponds to that.
