Mao visits the Shanghai Steel Plant. For a similar image, see the 1970 poster "Chairman Mao's heart and ours beat as one". Both follow up on Jin Shangyi's 1969 painting "Chairman Mao inspects Shanghai Steel Plant no. 3 (毛主席视察上钢三厂).
The painting was created by a group of Shanghai artists, led by Chai Zushun and including Ha Qiongwen, Lei Tan and Liu Kemin. They are not mentioned in the poster impressum.
