A four-stamp commemorative group from the USSR issued in 1985, each valued at 5 kopecks and celebrating major historical, cultural, and sporting milestones. The set includes tributes to the Stakhanovite labour movement, the global significance of the 1917 October Revolution, the 900th anniversary of the Ukrainian city of Lutsk, and the FIFA World Youth Football Championship. Rich Soviet graphic design, strong ideological themes, and vibrant colour schemes make this a desirable mini-collection for thematic collectors of labour history, revolutions, city anniversaries, and sports philately. A well-balanced representation of late-Soviet commemorative art.
