Angrily denounce the monstrous crime of usurping the power of the Party by the "Gang of Four" anti-Party clique!, 1976

The 'Gang of Four' (四人帮, Sirenbang) was formed by Mao Zedong's wife Jiang Qing (1913-1991), the Shanghai Propaganda Department official Zhang Chunqiao (1917-2005), the literary critic Yao Wenyuan (1931-2005) and the Shanghai security guard Wang Hongwen (1935-1992). They rose to power during the Cultural Revolution (1966-1976) and dominated Chinese politics during the early 1970s.

We must certainly wage the great struggle of exposing and criticizing the "Gang of Four" to the end, 1977

Ferreting out the "Gang of Four" to the satisfaction of the people, be merciless with bad people even if they're down and continue to advance on the enemy, 1977

After Mao's death in September 1976, they were arrested; in 1980 they were tried in court. Jiang Qing and Zhang Chunqiao, seen as the leaders, received (suspended) death sentences, while Yao Wenyuan and Wang Hongwen, considered the henchmen, were given lengthy prison sentences.

Our hearts turn towards Chairman Hua, relentlessly criticize the "Gang of Four", score a victory in production--A selection of art posters by workers of Yangquan, 1977

After the Gang was arrested, a massive propaganda campaign was launched to discredit them and praise Mao's successor, Hua Guofeng. Nonetheless, relatively few striking posters were produced to accompany the campaign, although that was not really necessary. Most people had suffered personally from their reign. The poster below is one of the the harshest and most explicit I've ever seen.

Resolutely overthrow the anti-Party clique of Wang (Hongwen), Zhang (Chunqiao), Jiang (Qing) and Yao (Wenyuan), 1976

Aside from an avalanche of cartoons poking fun at the four (cartoons being the favored medium for attacking political opponents), most posters consisted of scenes of jubilation or mass criticism. The poster below, produced in the famous New Year Print studio of Yangliuqing (Tianjin) in 1978, combines both cartoons and the traditional nianhua style.
