A barber pole is a cylindrical sign traditionally found outside barbershops. It features a spiral pattern of red, white, and blue stripes. The red symbolizes blood, the white represents bandages, and the blue is often interpreted as veins, reflecting the historical practice of bloodletting performed by barbers in the past. The pole's design dates back to the Middle Ages when barbers also acted as surgeons. Today, the barber pole serves as a recognizable symbol of barbering and grooming services, attracting customers to the shop. It remains a classic emblem of the barbering profession worldwide.
