Postage Due. 1931 (23 APR) Abdulhusein Esmailji printed blue/green cover (with bilingual Gujrati/English address) from MKOAN PEMBA to Zanzibar franked on reverse by 1926-30 3c black/orange postage dues x2 (R1/2 and 5/1 from corrected setting) overlapping an original strike of the despatch squared circle though tied by two further strikes; the cover and stamps with faults, still of good appearance, a unique and exceptional usage with there being no other instance of the usage of 1926-30 and 1930-33 postage due issues outside the Zanzibar G.P.O.
Note: a possible explanation, in the absence of any tax markings, is that postage dues were used as provisional postage stamps. Ex Griffith-Jones (discussed and illustrated as Fig 11.37 on page 318 of his book census f.102)
