It’s a cover that was clearly designed for Dune, and was published as a Dune cover and then later repurposed.

I actually thought that this:

would turn out to be a repurposed Man In the High Castle cover with a creepy doll face slapped on it, but it doesn’t show up here

so maybe it’s just supposed to be somebody’s idea of banding?
