A full shot of a piece of paper resting on a white wooden surface. The paper features a glossy, colorful graphic design with the words "SAPOS EM FLORESTA TROPICAL" at the top, indicating a theme of "Frogs in Tropical Rainforest". Below, four postage stamps are arranged in a row, each depicting a different species of frog. Each stamp shows the text "S. TOMÉ E PRINCIPE" along the bottom. The image is surrounded by illustrations of tropical plants, birds, and fungi, creating a dense jungle aesthetic.
