Пролетарии всех стран, соединяйтесь!
The slogan on the banner bears the Soviet Union state motto ("Workers of the world, unite!") in both the Russian and Azerbaijani languages. In Azerbaijani, it is "Бүтүн өлкəлəрин пролетарлары, бирлəшин!" (in the current Azerbaijani Latin script: "Bütün ölkələrin proletarları, birləşin!").
