VERY FINE. THE UNIQUE ERROR BLOCK AND THE KEY TO A KUWAIT COLLECTION. A BRITISH COMMONWEALTH RARITY OF GREAT IMPORTANCE.
A total of five sheets were found with varying degrees and stages of the error affecting the same bottom left positions such as this block. Two mint examples remain, the example offered here and a strip of four. The remaining three sheets went unnoticed and were subsequently used. Singles and pairs, while very rare, have been recorded. This block is illustrated in The Postal Agencies in Eastern Arabia and the Gulf by Neil Donaldson.
Offered for the first time in decades. Ex Ameer of Bahawalpur. Unpriced in Scott. SG value for a pair with one surcharge albino
