Description
Great Britain 1968 1s6d British Bridges error, SG765a.
Superb Post Office fresh unmounted mint, with full original gum, example with gold (Queen's head) omitted, offered with a normal example for comparison.
A rather unusual error, with the missing gold colour resulting in the Queen's head appearing in sky blue, which is the underlay colour, rather than gold.
A scarce and reasonably priced QEII stamp error. Pierron records only 120 known mint examples.
