Great Britain 1970 Literary Anniversaries error, SG826b.
A very fine unmounted mint, with full original gum, right hand marginal se-tenant block of four showing a complete omission of yellow-bistre (face value on David Copperfield) and a partial omission on the adjoining stamp (Oliver Twist).
Offered with an example of the normal block for comparison and display purposes.
The stamp issue was produced to commemorate the centenary of the death of Charles Dickens (1812-1870).
A very rare QEII error. Pierron records only 9 or 10 examples.
SG Catalogue Value: £4,000+.
