Here is the cover of CLAMP IN AMERICA, the guide book which claims to be “the definitive history of the manga superstarts in the U.S.A.”.

Good choice for the cover illustration, but I was expecting a new illustration. The colors look a bit twisted, but maybe it’s the picture, and the cover design overall looks ordinary to me.
According to the publisher Del Rey, the book will be released in March 2010, costing $27.99.
