Kodansha has the cover of the pocket edition version of Peter Pan & Wendy drawn by CLAMP:
The cover was taken from a puzzle game available at the Aoi Tori website. You can play it here if you want xD
CLAMP’s Peter Pan has belts in his clothes and Tinker Bell looks like Primera =) Clearly a Nekoi work here 😉
Apart from the cover, CLAMP was also in charge of drawing the inside illustrations.
The book will be released on November 17.
Thanks syaoranmew for the heads up!
