This 90 Pfennig commemorative stamp was issued by the Deutsche Bundespost (Federal Republic of Germany) in 1979 to mark the 100th anniversary of the birth of Paul Klee (1879–1940), one of the most influential modern artists of the 20th century. The design reproduces Klee’s 1924 artwork Vogergarten (“Bird Garden”), a delicate composition that combines abstract geometry with whimsical avian forms in earthy, harmonious tones. The stamp pays tribute to Klee’s unique blend of expressionism, cubism, and surrealism, reflecting his fascination with nature and imagination. The clean modern typography complements the artwork’s balance between playfulness and structure.
