Bay seniors who think there is nothing to laugh at when they read the newspapers might want to visit “Slinging Satire: Masters of Political Cartoons” at the Cartoon Art Museum through March 15. These young Herblocks include recent Pulitzer Prize winners, and a wide political spectrum working in both print and digital. Seniors $6. Meanwhile in Santa Rosa until April 26 there is a more benign cartoon show devoted to “Peanuts in Wonderland” at the Charles M. Schulz Museum. Seniors $5.
