Business cards, or some form or them, have been around since 15th century China when royals used them as a way to announce a visit to a town’s residents.
Around the 17th century, the use of “calling cards” spread to the masses, mainly as a way for a person to show that he or she had stopped by for a visit. But there were other uses for them too and the rules governing the size and shape of the calling card, when to leave it and when to send it followed a strict code.
