Thank you! I think it's the only crown on the shelf. There is also one special ring, though I don't think it's the gold one next to the crown. It makes the wearer invisible. The story this was painted for (it was the endpaper design for an illustrated children's book) is really a great one, a classic in England.
Rhonda, thank you very much! High praise. Unfortunately my book itself went out of print pretty quickly. And I thought I'd lost the endpaper files, but as soon as I came across them I decided to post on Spoonflower.
Your charming illustrations have captured the essence of the era in which this classic E. Nesbit story was set. Every detail of your delightful design is a reminder of what was one of my favourite fantasy stories when I was young!
