An artistic curiosity today. We see two versions of my Virtual Reality gamebook Down Among the Dead Men - or, in French, Le Pirate des Sept Mers. I remember that when I got some copies of the French edition, I was immediately struck by how much more powerful the cover image looked when mirror-flipped like that. And it reminded me of a book I wrote in the mid-80s to tie in with the TV series Knightmare. When my dad saw the cover, he turned it upside down and said, "See how much more threatening it looks?" He was right; try it for yourself and see. (Dad was an electrical engineer, incidentally, not an artist.)
In the case of the Dead Men cover, I don't know if the artist or the art director was responsible for the orientation on the English edition. I suspect the latter, because that would explain why ol' Billy Bones there has the sword in his left hand. Although to really have maximum impact, his head should be turned so he's facing us or looking over our right shoulder.
Incidentally, you can try the same mirror-flip trick on yesterday's Blood Sword cover.
