Universal Postal Union regulations have for many years allowed that mail posted ON THE HIGH SEAS, and bearing stamps of the same country whose flag the vessel flies, might be put ashore at the first port of call, where it is postmarked with the paquebot marking of that port and sent on its way to the addressee. The Republic of Korea, however, had not utilized paquebot mail until it was introduced there in late 1951 by Captain Charles E. Milbury, who is noted for his famous “Sea-Jug Post”.
I have been fortunate in acquiring examples of all the various types of Korean paquebot markings known to date. The first paquebot mail was sent from Pusan, Korea on December 25, 1951, and this mail was stamped with a special rubber stamp supplied by Capt. Milbury at his own expense. These first covers were questioned as to their authenticity by several writers in the philatelic press. This matter was cleared up by a letter from Rew, Wan Sik, an official of the Ministry of Communications, Republic of Korea, in which he stated that these covers of December 25, 1951 were the first accepted as paquebot mail by the Republic of Korea. I have never seen figures as to the number of covers posted on that date except reference to the ‘fact that the number was small.
