This is a Great Britain Penny Red issue, introduced in 1854 as a continuation of the famous Penny Black and its red successors. The stamp features Queen Victoria’s profile and is printed in a distinctive red shade. It bears the corner letters K – K, which identify its plate position. The cancellation is a “W32” barred numeral obliterator, used in the London district of West Central, making it a notable collectible for postmark specialists. Issued during the height of Victorian postal reforms, the Penny Red remains one of the most studied stamps in British philately.
