This is "Little Star Communication," a book by Yoshitomo Nara, a representative contemporary artist. It is already out of print and includes the obi (paper band). The obi shows some signs of aging, but the main body of the book and the poster are in near-new condition with very little damage. I purchased it and stored it without reading it much. Of course, the poster is also included. This is a very rare item, so please consider it for your collection.
