The Belgae Torc book cover image

This is the image of the torc that I used on the cover of my novel The Belgae Torc.  It's the closest picture that I could find based on my description in the book.  I didn't see this torc before I wrote the story, just relied on imagination.  It's pretty close to how I saw it, maybe a bit lighter.  The animal heads in my book are horses and there is a clasp between them, but I won't say too much as readers may want to imagine it as described.
This ancient artefact can be found in the Louvre in Paris.
I particularly like the way the colour on the cover is graded from white to gold and the gold and black lettering looks cool too.
