Hard to find art sets

I'm having trouble tracking down arts for some of my MVS carts. I figured I'd start a thread about arts that are hard to come by. I know that English Last Blade 2 art is very hard to find, but what else can be considered rare art?

Samurai Shodown IV english, realy all i ever see are the "spanish ones"

Waku Waku 7 can say i see it offen either.
