Bill Watterson is alive and age 60 but the final Calvin and Hobbes strip ran on Sunday, December 31, 1995. “Since the conclusion of Calvin and Hobbes, Watterson has taken up painting, at one point drawing landscapes of the woods with his father. He has kept away from the public eye and has given no indication of resuming the strip, creating new works based on the strip’s characters, or embarking on new commercial projects, though he has published several Calvin and Hobbes anthologies. He does not sign autographs or license his characters, staying true to his stated principles. In previous years, Watterson was known to sneak autographed copies of his books onto the shelves of the Fireside Bookshop, a family-owned bookstore in his hometown of Chagrin Falls, Ohio. He ended this practice after discovering that some of the autographed books were being sold online for high prices.” Wikipedia
