One of the most rewarding aspects of collecting is doing research on the images. I really enjoy probing the Internet to see what I can find out from the threads of information contained in the image. As a result, my general knowledge of things odd and unusual from all over the world is growing!

The coat of arms turned out to be British but these are not members of the British royal family. It was a Facebook friend who took a wild guess that this is ‘Fabiola of Belgium’. She turned out to be right. I looked up inbound state visits to the UK dating back to the 1950’s and learned that King Baudouin and Queen Fabiola of Belgium visited the UK from 14 – 17 May 1963. It was their last official visit to Britain. The slide was taken shortly after their arrival by royal train at Victoria station where they were met by Queen Elizabeth and then rode in a carriage procession to Buckingham palace.
