Bill Watterson has donated a signed copy of The Complete Calvin and Hobbes, including an original sketch, to a charitable Team Cul de Sac auction.
The rare sketch from Watterson is for Team Cul de Sac's June 15 HeroesCon Drink and Draw Auction, which helps raise money for the Michael J. Fox Foundation for Parkinson's Research. The fundraising event is held in honor of late Cul de Sac creator Richard Thompson, who fought an eight-year battle with Parkinson's Disease before passing away in 2016.
