At Windsor Castle, The Queen viewed a new portrait commissioned by the RAF Regiment to celebrate its 75th anniversary. The Queen, Air Commodore in Chief of the RAF Regiment, was painted by artist Stuart Brown in the White Drawing Room at Windsor Castle.
Her Maj in Windsor mode, with a double strand of pearls. (Tough to tell if she's wearing her usual earrings here; sometimes she goes for pearl studs instead.) And there's something of a double brooch situation: the Pearl Trefoil in real life and an RAF Regiment Badge in the painting. That brooch was presented to her by the regiment and
shows the Astral Crown and crossed Lee Enfield rifles.
