If you grew up watching cartoons between the ’60s and ’00s, you’ve seen Ron Campbell’s work. He’s animated everything from a Beatles television show and the film Yellow Submarine to Scooby Doo, The Flintstones, The Smurfs and Rugrats. After spending decades behind the animation, the craftsman has retired and embraced a second career as a painter. Now he’s traveling the world selling art and meeting the fans of the TV shows he helped create. Campbell will be at Bitfactory Gallery, 851 Santa Fe Drive, on Friday, August 11, from 4 to 8 p.m., Saturday, August 12, from noon to 6 p.m., and Sunday, August 13, from noon to 4 p.m, presenting his Beatles Cartoon Pop Art Show, with original cartoons of the Fab Four and artwork based on his fifty-year career.
