This poster was cut into four pieces with quite some loss of text and image, also at the top and bottom, and later reasssembled. Editorial information is missing. The exhibition was organized by the 西工人革命造反兵团新总部 - Western Workers' Revolutionary Rebel Corps New Headquarters - and held in the 联络地点红旗剧场后楼 - rear building of the Red Flag Theater. The location probably is Chengdu, Sichuan Province.
