This exquisite 1985 miniature sheet from Portugal was issued to celebrate the country's natural heritage and its participation in the Italia '85 international stamp exhibition. The central stamp, with a face value of 100 escudos, is set within a wider illustrated border depicting the tranquil dunes and coastal scenery of the Dunas de São Jacinto Nature Reserve. A pair of rabbits, native to the area, are featured as a symbol of the region’s biodiversity. Designed by C.A. Reque and printed by INCM, the sheet blends art and environmental awareness, making it a sought-after piece for thematic collectors of nature, fauna, and philatelic exhibitions.
