On Wednesday I got six postcards: one from the United Kingdom, one from Japan, one from Indonesia, two from Germany and one from Hong Kong.
The card from the United Kingdom shows different stamps showing Queen Elizabeth II. To commemorate Queen Elizabeth's achievement of becoming the longest reigning monarch in the British history a new First Class Definitive in Amethyst Purple with a "Long to Reign Over Us" overprint was issued on 9th September 2015. Two of the stamps are applied to the card.
The card was sent in a transparent envelope.
Thank You very much Pete!
