This striking 1986 Yugoslavia Europa issue features a detailed anatomical depiction of the human brain, symbolizing communication, knowledge, and intellectual exchange—the central theme of the CEPT Europa series that year. Designed by R. Bojanić, the artwork blends science with abstract landscape elements, reflecting the connection between human thought and global interaction. Issued by PTT Yugoslavia, this stamp stands out for its bold colors and conceptual depth. A fine example of thematic philately combining medicine, communication, and art. Highly collectible within both Europa and science-themed collections.
