Wall newspaper

These so-called "placard newspapers" are said to have begun due to a chronic shortage of newsprint paper resulting from war conditions, blockade, and economic dislocation.

[1] The papers were first used in military barracks as a means of disseminating official government information, but their use was soon common in factories, schools, and other locations where large numbers of people congregated.

[1] Wall newspapers were frequently used in factories of Communist East Germany during the second half of the 20th century as a mechanism for publicity and propaganda.

Under the reign of Mao Zedong, wall newspapers were "forward and full of pathos-filled propaganda about current events" and the "large victories for our grand nation", according to Qiu Xiaolong.
