I suspect every book with a dust jacket has variant dust jackets as designers tweak the design for the final edition. A lot of these probably aren't yet recognized by collectors as most of the rejected or trial designs stay within the publishing house. I suspect this is the case with the "yellow lettered" dj for THE DARK HALF.

In the case of ROSE MADDER there are several known variants. This first photo shows (on left) a proof dust jacket with King's name in black on the front panel and in red on the spine. This one is not in Beahm's last collectibles book.

On the right is a rejected design that has King's name in red on both the front panel and the spine. I think this was rejected because King's name didn't really stand out enough. Both of these have the book title in much larger letters than on the final design.
