I thought it would be helpful for you to see what's inside this book. So I put a bunch of Images above. This is a gorgeous book chock-full of gripping details about the subject matter and ridiculously close-up and detailed photography. [Ooops, rather than go crazy you'll have to tone it down a bit. Amazon deleted most customer-uploaded images from product pages in July 2013.]
First and foremost, it is a coffee table book that you can peruse at your leisure. Any page you turn to will have glorious pictures, most covering the entire leaf with captions and descriptions. The cover photo is of the official Imperial Crown made for King George VI, QEII's father, in 1937. It was sized down to fit her and is in current use. (See her coronation picture in Images.)
Second, it is a history of the Crown. Via examining the ancient inherited riches, it is a natural flow to explain the royalty in England, the world's premier monarchy. I have focused on the crowns in the Images but the other regalia including, orbs, scepters, robes, gifts, the extensive jewel collection and portraits help tell the entire story. The following appears in the book:
"The story of the royal family in the 18th century is a tale of fathers and sons. With chilling consistency, each generation loathed the next: George I was on lamentable terms with his son George II; George II detested his son, Frederick Prince of Wales, while Frederick's son George III, considered his heir, George IV, to be an imbecile."
My husband is from England and, coincidentally, soon after giving me this book for Christmas, my husband's sister mailed him a letter in the envelope shown above. With the recent issuance of the stamp which comprises the cover of this book, and with the Olympics, the royal wedding and Queen Elizabeth's Diamond Jubilee approaching, there is renewed interest in the glory of England. As a student of Tudor times and having a love of all that is British, I applaud this.
