cover 1903 (3 Dec.) official envelope (central filing crease) to Pola (28.12 arrival) showing the rare "K.U.K. GESANDSCHAFTS/WACHDETACHEMENT/PEKING" c.d.s. with error of spelling and corresponding two line sender's cachet in violet. A rarity, as the canceller with corrected spelling followed within two months. According to Dr. Ferchenbauer there are fewer than five examples recorded. Photo
