This commemorative stamp was issued by the Soviet Union to mark the World Congress of Trade Unions held in Havana, Cuba, in 1982. The design features interconnected globes symbolizing international solidarity, alongside stylized human figures representing unity among workers worldwide. The aircraft motif highlights global cooperation and movement between socialist nations during the Cold War era. Printed in bold Soviet graphic style, the stamp reflects political diplomacy through philately. It remains a strong thematic addition for collectors specializing in labour movements, international organizations, or USSR propaganda issues.
