Several online stores such as
Amazon have been listing the release date of CLAMP IN AMERICA to February 23, 2010. The official website of publisher Del Rey
confirms the postponement for such date.
Although no official word has been given, one of the reasons for the change could be due to the increase of page numbers. The book, that covers CLAMP's career during its 20 years of history and their impact in the American culture, was originally expected to have 144 pages. Now, it is being listed as having 336 pages (more than the double).
The price has been increased as well by extent, from US$ 19.99 to US$24.99.
Thanks to
