Issued by Germany (Deutsche Bundespost) in 1973, this striking stamp commemorates the 500th birth anniversary of Nicolaus Copernicus (1473–1543), the pioneer of the heliocentric theory. The bold red and black design features a portrait of Copernicus alongside a symbolic representation of the solar system, encircled by zodiac signs. This artistic layout reflects his revolutionary contribution to astronomy and the shift from geocentric to heliocentric understanding. The denomination of 40 Pfennig made it a commonly used commemorative issue of its time. A visually powerful and historically significant piece, it is highly valued among thematic collectors of science, astronomy, and famous personalities.
