Lunar 2 Eternal Blue cd art

I've heard theres at least 7 different versions of the cd art. I was wondering if anyone knew where I could find info on each of them and the various rarities.
only Silver Star (the first game) had the 7 different cd art's (and me being the sick freak i am have them all). Eternal Blue only has the lone art style. cant link to the page but working designs website has them shown in the museum section, sega cd, lunar silver star, details. hope this helps.
