A superb unmounted mint, with full original gum, imperforate top left hand corner marginal imprimatur with a ”BPMA” handstamp on reverse.
A scarce example from the first approved printing sheet for the issue.
Exceptional provenance as it was released from the British Postal Museum Archives in 2014. Prior to this it was stored in the museum archives in climate controlled vaults since being printed and is therefore in uncirculated mint condition.
