"'Calvin and Hobbes' is one of the most popular comic strips of all time. Over 30 million copies of 'Calvin and Hobbes' books have been sold all over the world. However, almost no other officially licensed 'Calvin and Hobbes' merchandise was ever released. Teaching with Calvin and Hobbes is the most unique, most desirable, and rarest of those few officially licensed items. The demand for 'Calvin and Hobbes' is enormous; the supply is miniscule. This book has the potential to be one of the most valuable books of all time....

"It seems unlikely that the book will ever be reprinted. However, a reprint, resulting in wide public awareness of the book, would only increase the value of this rare first edition."
