This 1918 envelope stamped Cape Town is in good antique condition. There is age related wear as with any antique piece. Borrowed from French paquebot (“mailboat”). First used in Great Britain in 1894, the term was adopted for general use by the Universal Postal Union in 1897. Paquebo postal marking or cancellation stamped on mail posted at sea or in a harbour for processing by the postal authorities at the next port of call.
