1940s black-and-white comedy noir theatrical poster. Classic noir photography with dramatic stage lighting. Smoky jazz club. Art-deco decor, cocktail tables, cigarette smoke, spotlights. Mike leans over grand piano using magnifying glass to inspect the keys, investigating a supposedly missing musical note, wearing rumpled suit, fedora, trench coat and glasses, his face showing the reference likeness. Lisa, glamorous in a fitted satin evening gown with long gloves, stands beside the pianist looking profoundly unimpressed, her face showing the reference likeness. The pianist points toward sheet music while saxophonist tries not to laugh. Jazz band in background. Title: THE CASE OF THE MISSING NOTE in classic noir typography.
