The manual has photos of the SD clay figures that the in-game graphics are based on.
I don't really get you, if your talking about the over screen characters, that is what over screen characters look like in most rpg games. The only other imagery of what the characters could have looked like is from the save screen.
Their are tons of hand drawn imagery in the game cut scenes, and instructional booklet, so I still do not understand. Unless you probably meant for, characters to look like action/display figures in their full comical/animated form, that is something else.
Earthbound, Phantasy Star, secret of mana II, and some other games also have clay figures made for them. So I do not understand.
I could imagine the costs to get super duper exprienced artists and make a whole toy line, instead of hiring somebody to make a diarama, featuring the characters. They would have also have them pose in various ways as well.
