I noticed when looking of an old auction image backside of an Enchanted Island Maiden Fairhair box.. that Maiden MistyCurls was not in it. But the backside image of the box MMC came in does have her in that illustration, but the illustration appear to have been pushed to the left side and slighted cut off there so she'd fit. The latter image is (a much smaller version of) the image that was so generously provided by a person on eBay btw so yes, I'm almost done with that wallpaper, but you can see from the image, the right side in particular is a pain to edit..

So one can certainly see that she has been placed there afterwards, not just due to the fact that she is sitting "on" one of the flower decorations that are in the foreground of the image.. MCC's assigned number is also a bit different than from the rest of the dolls in that series.

Which makes me wonder.. was MMC a very late addition to the Enchanted Island series or was this just bad planning on those responsible for making the backside illustrations on the box? Or is there another explanation?
