This definitive stamp features the iconic 'Wilding' portrait of Queen Elizabeth II, designed by Dorothy Wilding. The design is framed by national floral emblems: a thistle for Scotland, a daffodil for Wales, a shamrock for Northern Ireland, and a Tudor rose for England. This specific issue is distinguished by the vertical phosphor-graphite lines on the back, an experiment for automated mail sorting.

Issued during a period of postal modernization, these stamps were part of the Post Office's early experiments with automatic letter facing (ALF) technology, using phosphor lines to orient mail for cancellation.
