This Hungarian commemorative stamp, issued in 1981, honors the 1300th anniversary of the founding of the Bulgarian State (681–1981). The design features two emblematic medallions: an upper black medallion depicting the historic Madara Horseman, an early medieval Bulgarian rock relief, and a lower green medallion with a stylized Bulgarian lion symbolizing national continuity. Decorative laurel motifs frame the artwork, reflecting the celebratory nature of the issue. A notable thematic piece linking Hungarian and Bulgarian historical ties, making it a desirable addition for collectors of European history and anniversary issues.
