Great Britain 1973 3p British paintings (Self portrait - Sir Joshua Reynolds) error, SG931a.
Superb Post Office fresh unmounted mint, with full original gum, example with gold (Queen's head) omitted, offered with normal for comparison.
On all examples of the error, embossing is shifted 5mm right and bisects the perforations.
A scarce and reasonably priced QEII stamp error. Pierron records only 200 mint examples.
