Royal response from His Royal Highness The Duke of Edinburgh on the occasion of his and Her Majesty The Queen’s 72nd wedding anniversary. The wedding took place on 20th November 1947 at Westminster Abbey. I sent my letter on November 1st and received my reply on November 7th, which means it took just 7 days for this reply. The reply is in the form of a letter thanking me for my kind wishes and wishing me the best. The letter is signed by Mrs. Suzy Lethbridge who is the Correspondence Secretary to The Duke of Edinburgh.
