Personally, I love this cover - don’t know who did it (someone at fanedit.org?) - though could easily be adaptable in a Triple Feature cover? (with permission, of course)…
I have been looking for the higher quality version of this cover forever now, and I have had no luck!
Have found it on here (and available for download too), mate:-
