Suggestions on the use of signs in various media
William Kenkston, a British publisher, printed advertisements promoting religious books and posted them on the streets of London, which marked the beginning of western printing advertisements. The content of the advertisement is as follows: "If anyone, inside or outside the church, is willing to get a ceremony book suitable for Sansbury Cathedral and uses the same font as the users of this advertisement, please drive to Westminster to buy it. The price is low, there is a shield at the sale place, and one line runs through it, which is easy to identify. "
