During which century did the practice of putting signs on buildings and businesses begin?

Answer 1

The practice of putting signs on buildings and businesses began to emerge prominently during the 14th century in Europe. While signs and symbols have been used in various forms for centuries prior to that, the 14th century saw a notable increase in their use as a means of commercial identification, especially in growing urban areas. This trend continued to develop, particularly with the rise of merchant and trade activities during the Renaissance.
