"This book is printed on 60# white paper with an eggshell finish, processed by Walker Paper, one of Pennsylvania’s six largest paper processors. The human touch of proprietor Norman Walker can be seen throughout the pages, but particularly in the tiny nick on the upper-right hand corner of page 33, where Norman inadvertently gave himself a paper cut.
The paper was pulped from a field of Norway Spruce grown in Mifflinville, Penn. The tree that became this particular book was a 37-year-old spruce, tall and sturdy, by the name of Larry. Larry was a happy tree, home to children who enjoyed swinging from a tire attached via rope to one of his lower branches. The marks from the rope can be witnessed in the upper left-hand corners of pages 134 and 136."
