1940s black-and-white comedy noir theatrical poster. Rain-soaked city sidewalk at night. Hard rim lighting, deep shadows, exaggerated detective seriousness, classic film grain. Mike stands beneath a streetlamp examining rain droplets on the pavement through a magnifying glass, wearing a rumpled suit, fedora and glasses, his face showing the reference likeness. Lisa is glamorous in a fitted dark trench dress, stockings, heels and gloves, holding her own umbrella, giving Mike an exhausted sideways look, her face showing the reference likeness. The supposedly missing umbrella is plainly tucked under Mike's arm. Background: taxis, pedestrians with umbrellas, neon hotel sign, steam from street grate, police officer, wet asphalt reflecting lights. Title: THE CASE OF THE STOLEN UMBRELLA in classic noir typography.
