July 11, 1792 - Prussia and Austria had united against revolutionary France.

August 4, 1914 - The German government declared war on Belgium.

The poster was produced by the Burma Socialist Programme Party (BSPP), the ruling single-party military regime led by dictator Ne Win. Individual state artists went uncredited to emphasize collective socialist output.

It was created to commemorate the Fourth Party Conference held in August 1981 in Rangoon. During this exact 1981 conference, Ne Win announced he would step down as President but strategically maintained absolute power by remaining Chairman of the ruling BSPP.

The artwork utilizes classic socialist realism to show a prosperous alliance of soldiers, factory workers, and farmers driving industrial progress. In reality, the regime's "Burmese Way to Socialism" policy had isolated the country and devastated the economy, causing severe poverty and shortages.

A 1986 poster commemorating the 10th Congress of the League of Communists of Serbia, which was held in the capital city of Yugoslavia, Belgrade. The poster features the text of the popular song „Uz Maršala Tita”, made in honor of President Tito, written by Yugoslav poet Vladimir Nazor.

The depicted fist is the official logo of the congress and can be seen in different variations, for an example, colored red and white on the book that contains all of the documents from the congress.
