Auction # 2027 ARGENTINA: Special July auction

15/AP/1877 Buenos Aires - Bordeaux: Cover sent by British mail with single domestic rate of 8c. (GJ.47, with minor defects) cancelled "BUENOS AIRES OM 15/AP/1877" and international rate to by paid by addressee. In London it was marked for postage dues BY MISTAKE with "T1.10" corresponding to letters from the Caribbean, with Calais transit mark and on back Calais-Bordeaux cancel. The addressee had to pay higher postage dues than what was due, because the French mail persisted on the mistake made by the British mail by handstamping "17" (1.70Fr.) instead of the correct "12", very nice and interesting piece for the specialist!
