Issued by the German Democratic Republic (DDR) in 1969, this elegant three-stamp set celebrates Geschützte heimische Pflanzen (Protected Native Plants). Designed by renowned illustrator Klemke, each stamp features a delicately drawn species against a striking black background: the 10 Pfennig depicts the Gentiana pneumonanthe (Marsh Gentian) in vivid blue, the 20 Pfennig portrays Cephalanthera rubra (Red Helleborine) in crimson tones, and the 25 Pfennig shows Arnica montana (Mountain Arnica) in bright yellow. The series emphasizes East Germany’s commitment to nature conservation and botanical heritage, combining scientific accuracy with refined artistic minimalism.
