(AP) DALLAS - DALLAS (AP) â€” Artwork from "Calvin and Hobbes" creator Bill Watterson's three-day return to comics has brought more than $74,000 at auction to benefit Parkinson's research.
Dallas-based Heritage Auctions says the three comic strips sold Friday for a combined $74,040 to three collectors, all of whom wish to remain anonymous. Heritage had expected the strips to sell for more than $30,000 combined.
Watterson collaborated with "Pearls Before Swine" cartoonist Stephan Pastis in June after a long absence from the funny pages.
The artwork was sold on behalf of Team Cul de Sac, a charity established in honor of cartoonist Richard Thompson, who has Parkinson's. Proceeds will go to the Michael J. Fox Foundation for Parkinson's Research.
"Calvin and Hobbes" ended in 1995.
