I just looked through a crappy PDF scan of the American manual, and this is the only image out of the Japanese ones I've been posting that doesn't appear in there. The American box art does appear at the beginning of the manual (and in full color too, unlike anything else but Nintendo's Seal of Quality), so I imagine they replaced this with that one. As much as I like seeing different portrayals of a game's art, I think that sucks when they could have included it in there to fit in with the look of the rest of the manual.
