black characters in the red squares: 帮助党整風! - Bangzhu dang zhengfeng! - Help the party's rectification!
white characters on the blue banner: 向資本主义前進 - Xiang ziben zhuyi qianjin - Forge ahead to capitalism.
on the bucket: 污蔑 - Wumie - slander.

Texts in the right part:
on the red banner: 社会主义建設 - Shehui zhuyi jianshe - Socialist construction
on the book: 馬列主义 - Malie zhuyi - Marxism-Leninism.

The impressum mentions Zhang Zhimin as "responsible editor" (責任編輯 章志敏).
