Great Britain 1971 7½p Christmas error, SG896a.
Superb Post Office fresh unmounted mint, with full original gum, example with gold (Queen's head) omitted, offered with normal for comparison.
The missing colour results in the loss of the Queen's head.
An iconic and scarce QEII stamp error, which appears very reasonably priced in the context of its rarity. Pierron records only 106 mint examples.
