Classic 1920s Harlem Barbershop Scene with Color-Popping Barber Pole

Classic 1920s Harlem barbershop interior scene in full black-and-white / sepia tone except for the vibrant spinning barber pole (bright red, white, and blue stripes with glowing motion blur) which is the ONLY thing in full color. At least three dapper barbers in vintage aprons and white shirts actively cutting hair with scissors and clippers, chatting and laughing animatedly with customers in the classic leather chairs, mirrors reflecting the busy shop, vintage posters and tools on the walls, warm wooden floors, soft natural window light, highly detailed cinematic AI art, elegant semi-transparent calligraphy watermark "BicRevelation" in the lower-left corner at golden-ratio offset 0.04 from left and 0.03 from bottom, height exactly 0.02 of image height, semi-transparent and unobtrusive.
