元代是我国传统戏曲繁荣时期,不仅剧目多,创作者多,而且有比较固定的演出场所——勾栏,在演出前常常向观众预告,这种预告演出的古老海报形式就是招子,有时候也叫招贴或招帖。招子主要悬挂或张贴在勾栏、茶肆和通衢大道上,预告伶人姓名、演出时间及演出剧目等内容,已与现代海报意义相同。 The Yuan Dynasty is a period of prosperous traditional drama in our country. Not only the repertoire but also the creators are many, and there is a relatively fixed performance place - the gillette. Before the performance, it often forewarn the audience. Also called poster or placard. The main hanging or posted on the hook bar, tea house and the thoroughfare Avenue, predictions of the actor’s name, performance time and repertoire and other content, and modern posters have the same meaning.
