Animation World News interviewed Tadahiro Uesugi, a Japanese illustrator who spent over a year creating concept images for Coraline. AWN also posted quite a few of Uesugi's images. Above, you can see his depiction of Coraline, her Other Father, and the self-playing piano (which is very different from
the version in the film). Most interesting comment:
I haven't had a chance to meet Neil Gaiman himself, but I drew the designing process upon the story of the Coraline book released in Japan. (By the way, illustrations of the Japanese version of Coraline book are done by a Japanese illustrator.)
I believe
this is the Japanese version of Coraline:

I couldn't find a copy at America's Amazon or eBay sites. And I also couldn't find any more information on the artist for the Japanese version. According to Google's
translation of the Amazon Japan page, the book is written by author "Neal Gay Man." The title of the book is translated as "Witch of the button and KORARAIN."
Anyway, at least when I looked at the AWN site, it was graced with the only banner ad I've ever enjoyed - - featuring real world and Other Bobinksy. It'll be a darn shame if there's never a real world Bobinsky toy made.
If you like Uesugi's art, you should also check out the slide show at
Metropolis I previously mentioned. It featured at least one painting not posted at AWN.
Finally, in other Coraline news,
here's another pair of Nike Dunks. Apparently a small percentage will feature large buttons. Seems like a bad idea to make a small percentage extra unique - - the people who win the "mundane" pairs will be left with a bitter feeling.
