Great Britain 1934 1d scarlet (large format), imprimaturs SG440var.
A superb unmounted mint, with full original gum, bottom left hand corner marginal "V34, Cyi. 2 Dot " control block of six perforated imprimaturs with "BPMA" handstamps on reverse.
A scarce control block 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.
