well, if anyones bought the new skinnie raiders, you'll notice they use stickers and stick them to a generic box with no pictures on it except for a skinnie, a warrior bug and a cap trooper on the sides (1 on each).
It looks rather tacky.
I like a mix of both, art on one side, blending into the miniatures on the other. But generally, I prefer minis on the front, It makes me pick it up, and look onto the back for better pictures. :wink:
