This elegant commemorative stamp from Austria marks the 100th anniversary of the General Directorate for the Post and Telegraph Administration. Issued around 1950–1951, it features a finely engraved view of the central administrative building in Vienna, rendered in detailed black-brown tones. The imperial double-headed eagle appears prominently above, symbolizing Austria’s long postal heritage. Designed with precision by O. Zeiller and G. Wimmer, it is a classic mid-century Austrian engraving prized for its architectural and historical significance. A desirable piece for collectors specializing in postal history, European administrative commemoratives, or Austrian post-war issues.
