Description: This vintage commemorative postage stamp from the People's Republic of Bulgaria (НР България) is an artistic piece belonging to a popular multi-value topical set highlighting regional marine wildlife. The graphic illustration features two Mediterranean monk seals (Pelagius monachus) swimming fluidly through brackish water, which is represented by a repeating, soft green wavy pattern. The foreground prominently captures a larger adult seal mid-glide with its spotted underside and sleek dark coat exposed, while a smaller companion echoes its motion in the upper right. Across the top border, the Cyrillic text "ЧЕРНОМОРСКИ ТЮЛЕН" (meaning Black Sea Seal) is seamlessly accompanied by its historic scientific designation, Pelagius monachus. The issuing country name "НР БЪЛГАРИЯ" anchors the lower frame next to a bold, dark typeface indicating the denomination of 2 stotinki (abbreviated as "ст 2").
Circa: 1961
Condition: Unused - hinged
Notes:
Biologically, the stamp carries a bittersweet significance for the region: the unique Black Sea population of the monk seal, which nested in sea caves along Bulgaria's rugged Cape Kaliakra, faced steep declines from coastal development and overfishing, making this specific item an enduring symbol of 20th-century European conservation efforts.
