1940s black-and-white comedy noir theatrical poster. Classic monochrome, bright practical highlights against deep black shadows, rich film grain. Chrome diner after midnight. Mike examines an empty plate with magnifying glass and fingerprint powder, wearing a rumpled suit, fedora and glasses, his face showing the reference likeness. Lisa sits on a counter stool beside him, glamorous in a fitted blouse and dark pencil skirt, quietly eating the missing sandwich while watching Mike investigate, her face showing the reference likeness. Waitress behind counter struggles not to laugh. Cook peers through kitchen window. Background: coffee urns, jukebox, rain outside, venetian blinds, cigarette smoke. Title: THE CASE OF THE STOLEN SANDWICH in classic noir typography.
