This is a short advertisement for 'Picture Post' magazine (shown to cinema audience before a film). Magazine's critics liked tonight's film.
A close up of the front page of a copy of Picture Post magazine with superimposed title: "Picture Post Welcomes You". As the title fades out, two new copies of 'Picture Post' (one with a very handsome Marlon Brando on the front page). A hand opens a magazine to reveal columns inside. Voiceover expresses hope that "you [audience] will like it [tonight's film] as much as they [magazine critics] do."
