AH!!! Thanks for that!! The pic I remembered showed Elizabeth from the rear-side, but it could have been this one. (It was a long time ago!) But it shows what a unique woman the Queen is. Thanks for the research. I’m glad we have it in print!
Happy to help! Getty Images had some others, so I am sure there are many photos from that day. It was a little tricky finding the right search term, which led me to the book, and then the photo.
