(Relaxnews) - Bill Watterson of "Calvin and Hobbes" fame has made a rare return by supplying the poster art for upcoming comic book documentary "Stripped."

The writer and director of "Stripped," Dave Kellett, is the creator of popular webcomics "Sheldon" and "Drive" and appeared in the 2013 documentary "Dear. Mr Watterson."

Watterson was known for his long-held belief that his cartoons were more important than the merchandising or licensing opportunities they afforded him. "Calvin and Hobbes" ran as a syndicated strip from 1985 to 1995, and since then the writer and illustrator has remained largely anonymous, hidden from the public eye.

But Watterson is to appear within "Stripped" itself, which contains conversation with more than 80 experts on the form, from professional peers such as Jim Davis ("Garfield"), Cathy Guisewite ("Cathy") and New Yorker staff cartoonist Roz Chast, alongside influential webcomic creators like Matt Inman ("The Oatmeal"), Ryan North ("Dinosaur Comics"), Zach Weiner ("Saturday Morning Breakfast Club") and Kate Beaton ("Hark! A Vagrant").
