The video shows a commemorative stamp sheet from São Tomé e Príncipe depicting dolphins ("Golfinhos" in Portuguese). The sheet features a central stamp portraying the Amazon river dolphin (Inia geoffrensis) with a value of Db 86000. Around the stamp, the sheet is decorated with images of other dolphin species, coral reefs, and marine life, set against a blue, underwater background. The sheet is placed on a wood-grain surface, suggesting a tabletop or a similar flat surface.
