Everyone is familiar with the symbol of the modern barbershop – shiny, white, blue and red cylinder rotating in front of the barbershop. The roots of this item goes to the distant past, when the barbers not only cut beards and mustaches, but also engaged in bloodletting, pulled teeth, put the patient enemas and leeches, the blood-soaked bandages after the procedure being posted on the street, so that the local folk knew that the barber works here.
