Twenty years ago, the Charles M. Schulz Museum was founded to preserve the work and history of the beloved cartoonist after which it is named. The museum is celebrating its two-decade anniversary with a Cartoon-a-Thon, which will feature live cartooning games, a chance to meet famous cartoonists like New York Times bestselling authors Raina Telgemeier and Reza Farazmand (illustrator of the above cartoon), and a photo shoot with Snoopy. The event will be held on August 6, 10 a.m.–5 p.m., at the museum in Santa Rosa; tickets are $5–$12 (free for ages three and younger).
