The Far Side 1997 Off The Wall Calendar by Gary Larson
Original and genuine
Used and in OK condition - please see photos
As far as I can tell, it is complete with no days missing.
You can see from the photos that only the first half of the year was "used".
As far as I can tell, only the top page has any hand-writing on it.
I did not want to look through all pages as I might damage them.
