Query: Oldie, but goodie

We were thrilled to find this childhood book. My grown siblings and I had fond memories of reading it with my dad and bought it for him for Christmas. It is a hard to find book and we were surpised to find it in a new hardcover. Very intriguing pictures and story about poor Treehorn who myseriously begins shrinking. Our children range in age 1 to 13. The books is a lenghty picture book and seemed best suited for prek-2nd grade, although our 4th graders seemed to understand its humor best.
