SG 354 1/2d Deep Yellow Green N14 (-) Watermark Royal Cypher sheet marginal in Post Office fresh unmounted mint condition.

A clean, original Hendon Certificate (24624) accompanies this unlisted shade and obviously a limited number of collectors who seek to go beyond the already extensive and comprehensive specialised shades.

Arrived here on card stating to be an ex Q 21 Perforated Control, though of course no way of verifying that fact.
