Any issue from the genuine state of Upper Yafa dated after 1967 is bogus,
It was part of the South Arabian Protectorate and absorbed (1967) into the PR of Southern Yemen
(later became the PDRY). In 1990 North and South Yemen merged to form the Republic of Yemen.
Genuine postal service was short lived in 1967, but the first Upper Yafa issue did see postal use for a few months.
I have a genuine commercial cover buried somewhere in my hoard of covers.
On September 30, 1967, the Sultanate of Upper Yafa, the only western state under the Protectorate not to
accept integration in the Federation, issued a series of 10 stamps from 5 to 500 fils (airmail from 75 to
500 fils) depicting a map of the state and its flag, as well as the state's coat-of-arms.
At the same time, the forces of the National Liberation Front had succeeded in pushing aside the Liberation
Front of Occupied South Yemen, taking control of the small sultanate of 600 square miles.
With American assistance, the Sultanate later (1967) issued 12 thematic series representing a total of
72 stamps. The large majority of these thematic vignettes were never used for valid postage.
Many years later, (1998-2005) a private individual in N.Z. took the name Sultanate of Upper Yafa to create a
cinderella state with new "stamps". The currency was in Omani Riyals.
