8-3/8x10.75" softcover w/200 pages.

Book reprints 57 "Calvin And Hobbes" comic strips by Bill Watterson. Owing to Watterson's principled refusal to license his comic strip for merchandise a license was only granted to the authors of this book after they personally communicated to Watterson the success they had using his comic strip to teach children w/learning disabilities. Unused and Exc. Published in a limited print run of just 2,500, only around 20 copies still exist, making this publication a very rare and highly sought-after book.
