When you think of a royal mace in my ebook, Gettysburg Passage, you may think of an image of an ancient and mysterious small staff or club that a king or royal functionary might wield as a symbol of authority. During the Viet Nam War the fighter jet above was a member of an attack squadron called the Royal Maces. You can clearly read the words on the side of the plane!

But then, a royal mace also looked something like the more royal and sedate image above. :-)
