History
The seals were created by the ancient populations of Egypt and Mesopotamia and Ancient Egypt ( scarabs and cylinder seals). Made of stone, metal or ceramic materials, they allowed to seal letters and various registers.
The invention of the press, with the appearance of mobile types, helped to massify the label. Over time, some stamps began to include a pad that features the ink being used, making it easier to use.
