They're back: Calvin, the six-year-old dirty tricksmeister and master of indignation and his warm, cuddly philosopher sidekick, Hobbes, a tiger whose idea of adventure is to lie on his back by the fire and have his stomach rubbed. In six short years this unlikely due has captured the hearts, the minds, and, most of all, the funny bones of America. They are the msot phenomenal success story in syndication - and publishing - history. In only six years, they appear in more than 2,100 newspapers worldwide, and Calvin and Hobbes wins as many readership polls as Calvin has excesses. All seven of Bill Watterson's collections have sold a million copies within a year of publication. This treasury collection contains a never-before-published full-color section, as well as the cartoons appearing in The Revenge of the Baby-Sat and Scientific Progress Goes "Boink." All Sunday cartoons are presented full-page and full-color.
