This striking 1933 Bulgarian commemorative set was issued for the IX Youth Sports Congress held in Sofia, showcasing classical-style athletic figures symbolizing strength, discipline, and national vitality. Printed in bold Art-Deco inspired designs, the stamps reflect Bulgaria’s interwar emphasis on youth, physical culture, and civic pride. The set includes three denominations (7, 4, and 14 Leva), each depicting a different athletic pose with monumental architectural backdrops. A desirable early European sports-themed issue, popular with collectors of Olympics, youth movements, and propaganda-era philately. Ideal for thematic collections and Balkan postal history.
